Abstract
BACKGROUND Impact of gender on heart remodeling after acute coronary syndrome (ACS) and consequently on development of heart failure (HF) remains to be elucidated. METHODS CORALYS is a multicenter, retrospective, observational registry enrolling consecutive patients admitted for ACS and treated with percutaneous coronary intervention. HF hospitalization was the primary endpoint while all-cause mortality and the composite endpoint of incidence of first HF hospitalization and cardiovascular mortality were the secondary ones. RESULTS Among 14,699 patients enrolled in CORALYS registry, 4578 (31%) were women and 10,121 (69%) males. Women were older, had more frequently hypertension and diabetes and less frequently smoking habit. History of myocardial infarction (MI), STEMI at admission and multivessel disease were less common in women. After median follow up of 2.9 ± 1.8 years, women had higher incidence of primary and secondary endpoints and female sex was an independent predictor of HF hospitalization (HR 1.26;1.05-1.50; p = 0.011) and cardiovascular death/HF hospitalization (HR 1.18;1.02-1.37; p = 0.022). At multivariable analysis women and men share as predictors of HF diabetes, history of cancer, chronic kidney disease, atrial fibrillation, complete revascularization and left ventricular ejection fraction. Chronic obstructive pulmonary disease (HR 2.34;1.70-3.22, p < 0.001) and diuretics treatment (HR 1.61;1.27-2.04, p < 0.001) were predictor of HF in men, while history of previous MI (HR 1.46;1.08-1.97, p = 0.015) and treatment with inhibitors of renin-angiotensin system (HR 0.69;0,49-0.96 all 95% CI, p = 0.030) in women. CONCLUSIONS Women are at increased risk of HF after ACS and gender seems to be an outcome-modifier of the relationship between a variable and primary outcome.

Abstract
Background The impact of complete revascularization (CR) on the development of heart failure (HF) in patients with acute coronary syndrome and multivessel coronary artery disease undergoing percutaneous coronary intervention remains to be elucidated. Methods and Results Consecutive patients with acute coronary syndrome with multivessel coronary artery disease from the CORALYS (Incidence and Predictors of Heart Failure After Acute Coronary Syndrome) registry were included. Incidence of first hospitalization for HF or cardiovascular death was the primary end point. Patients were stratified according to completeness of coronary revascularization. Of 14 699 patients in the CORALYS registry, 5054 presented with multivessel disease. One thousand four hundred seventy-three (29.2%) underwent CR, while 3581 (70.8%) did not. Over 5 years follow-up, CR was associated with a reduced incidence of the primary end point (adjusted hazard ratio [HR], 0.66 [95% CI, 0.51-0.85]), first HF hospitalization (adjusted HR, 0.67 [95% CI, 0.49-0.90]) along with all-cause death and cardiovascular death alone (adjusted HR, 0.74 [95% CI, 0.56-0.97] and HR, 0.56 [95% CI, 0.38-0.84], respectively). The results were consistent in the propensity-score matching population and in inverse probability treatment weighting analysis. The benefit of CR was consistent across acute coronary syndrome presentations (HR, 0.59 [95% CI, 0.39-0.89] for ST-segment elevation myocardial infarction and HR, 0.71 [95% CI, 0.50-0.99] for non-ST-elevation acute coronary syndrome) and in patients with left ventricular ejection fraction >40% (HR, 0.52 [95% CI, 0.37-0.72]), while no benefit was observed in patients with left ventricular ejection fraction ≤40% (HR, 0.77 [95% CI, 0.37-1.10], P for interaction 0.04). Conclusions CR after acute coronary syndrome reduced the risk of first hospitalization for HF and cardiovascular death, as well as first HF hospitalization, and cardiovascular and overall death both in patients with ST-segment elevation myocardial infarction and non-ST-elevation acute coronary syndrome.

Abstract
BACKGROUND AND OBJECTIVES Endocrine complications have been described in patients affected by RASopathies but no systematic assessment has been reported. In this study, we investigate the prevalence of endocrine disorders in a consecutive unselected cohort of patients with RASopathies. STUDY DESIGN 72 patients with a genetically confirmed RASopathy (Noonan syndrome [NS], N=53; 29 LEOPARD syndrome [LS], N=2; cardiofaciocutaneous syndrome [CFCS], N=14; subjects showing co-occurring pathogenic variants in PTPN11 and NF1, N=3) and an age- and sex-matched healthy controls were included in the study. Endocrine system involvement was investigated by assessing the thyroid function, pubertal development, auxological parameters, adrenal function and bone metabolism. RESULTS Short stature was detected in 40% and 64% of the NS and CFCS subcohorts, respectively. Patients showed lower Z-scores at DXA than controls (p<0.05) when considering the entire case load and both NS and CFCS groups. Vitamin D and Calcitonin levels were significantly lower (p< 0.01), Parathormone levels significantly higher (p<0.05) in patients compared to the control group (p<0.05). Patients with lower BMD showed reduced physical activity and joint pain. Finally, anti-TPO antibody levels were significantly higher in patients than in controls when considering the entire case load and both NS and CFCS groups. CONCLUSIONS The collected data demonstrate a high prevalence of thyroid autoimmunity, confirming an increased risk to develop autoimmune disorders both in NS and CFCS. Reduced BMD, probably associated to reduced physical activity and inflammatory cytokines, also occurs. These findings are expected to have implications for the follow-up and prevention of osteopenia/osteoporosis in both NS and CFCS.

Abstract
BACKGROUND Abnormalities of the immune system are rarely reported in patients affected by RASopathies. Aim of the current study was to investigate the prevalence of immune system dysfunction in a cohort of patients affected by RASopathies. STUDY DESIGN A group of 69 patients was enrolled: 60 at the Federico II University, Naples, 7 at University Magna Graecia of Catanzaro, 2 at "Scuola Medica Salernitana", Salerno. An age- and sex-matched control group was also enrolled. Autoimmune disorders were investigated according to international consensus criteria. Immune framework was also evaluated by immunoglobulin levels, CD3, CD4, CD8, CD19, CD56 lymphocyte subpopulations, autoantibodies levels and panel of inflammatory molecules, in both patients and controls. RESULTS Frequent upper respiratory tract infections were recorded in 2 patients; pneumonia, psoriasis and alopecia in single patients. Low IgA levels were detected in 8/44 patients (18.18%), low CD8 T cells in 13/35 patients (37.14%). Anti-tg and anti-TPO antibodies were detected in 3/24 patients (12.5%), anti r-TSH in 2 cases (8.33%), all in euthyroidism. Serum IgA and CD8 levels were significantly lower in patients than in controls (p 0.00685; p 0.000656 respectively). All tested patients showed increased inflammatory molecules compared to controls. These findings may anticipate the detection of overt autoimmune disease. CONCLUSIONS Patients affected by RASopathies are at risk to develop autoimmune disorders. Routine screening for autoimmunity is recommended in patients with RASopathy.

Abstract
Time to improvement is a crucial characteristic for effective treatments of chronic inflammatory conditions, such as psoriasis. Apremilast is a recently approved drug, belonging to the small molecule phosphodiesterase 4 inhibitors, whose optimal safety and efficacy profile is somewhat affected by slow activity rate in clinical trials. Real world case series are suggesting a more consistent improvement, and with this additional personal investigation on 48 patients, we signal that 58% of patients achieved Psoriasis Area and Severity Index (PASI) 50, and 19% PASI 75 improvement in the first 8 weeks of treatment. Results at 16‐week are remarkable, with overall 55% of patients achieving PASI 75, 21% PASI 90 and 14% PASI 100. Only 8 patients (18, 6%) had slightly improved, although satisfied with the regimen, and determined to continue. Noteworthy, our population was rather problematic in terms of comorbidities (86%), and resistance to other treatments, with only 28% naïve to systemics, including biologics. Moreover, the observation period includes the Italian outbreak of COVID‐19 epidemic, and further information on apremilast safety are provided, no one of the patients having stopped treatment. In such a critical period, the apremilast satisfactory speed of therapeutic response in a real‐world setting has further strengthens patient's compliance to remain safely at home, which is the best strategy to limit contagion.

Abstract
Sensorineural hearing loss (SNHL) is a common defect with a multifactorial etiology. Congenital cytomegalovirus infection (cCMV) is the most common infectious cause, and its early detection allows a prompt pharmacological treatment that can improve hearing prognosis. In a consistent percentage of profound SNHL, genetic causes and/or inner ear malformations are involved; their prompt diagnosis might change therapeutic options. This study reports a case of a 3- year-old female patient with symptomatic cCMV infection who also exhibits developmental delay, dysmorphic facial features, bilateral hearing loss, and cochlear incomplete partition, type 2, in 7q21.3 deletion. This deletion includes the genes DLX5 and DLX6 , which could be the candidate genes for the ear malformation named incomplete partition, type 2.

Abstract
We provide data on fetal growth pattern on the molecular subtypes of Beckwith-Wiedemann syndrome (BWS): IC1 gain of methylation (IC1-GoM), IC2 loss of methylation (IC2-LoM), 11p15.5 paternal uniparental disomy (UPD), and CDKN1C mutation. In this observational study, gestational ages and neonatal growth parameters of 247 BWS patients were compared by calculating gestational age-corrected standard deviation scores (SDS) and proportionality indexes to search for differences among IC1-GoM (n = 21), UPD (n = 87), IC2-LoM (n = 147), and CDKN1C mutation (n = 11) patients. In IC1-GoM subgroup, weight and length are higher than in other subgroups. Body proportionality indexes display the following pattern: highest in IC1-GoM patients, lowest in IC2-LoM/CDKN1C patients, intermediate in UPD ones. Prematurity was significantly more prevalent in the CDKN1C (64%) and IC2-LoM subgroups (37%). Fetal growth patterns are different in the four molecular subtypes of BWS and remarkably consistent with altered gene expression primed by the respective molecular mechanisms. IC1-GoM cases show extreme macrosomia and severe disproportion between weight and length excess. In IC2-LoM/CDKN1C patients, macrosomia is less common and associated with more proportionate weight/length ratios with excess of preterm birth. UPD patients show growth patterns closer to those of IC2-LoM, but manifest a body mass disproportion rather similar to that seen in IC1-GoM cases.

Abstract
BACKGROUND Glycogen storage disease type 1 (GSD1) is a rare and genetically heterogeneous metabolic defect of gluconeogenesis due to mutations of either the G6PC gene (GSD1a) or the SLC37A4 gene (GSD1b). Osteopenia is a known complication of GSD1. OBJECTIVES The aim of this study was to investigate the effects of poor metabolic control and/or use of GSD1-specific treatments on bone mineral density (BMD) and metabolism in GSD1 patients. METHODS In a multicenter, cross-sectional case-control study, we studied 38 GSD1 (29 GSD1a and 9 GSD1b) patients. Clinical, biochemical and instrumental parameters indicative of bone metabolism were analyzed; BMD was evaluated by dual-emission X-ray absorptiometry and quantitative ultrasound. RESULTS Both GSD1a and GSD1b patients showed reduced BMD compared with age-matched controls. In GSD1a patients, these abnormalities correlated with compliance to diet and biochemical indicators of metabolic control. In GSD1b patients, BMD correlated with the age at first administration and the duration of granulocyte colony-stimulating factor (G-CSF) therapy. CONCLUSIONS Our data indicate that good metabolic control and compliance with diet are highly recommended to improve bone metabolism in GSD1a patients. GSD1b patients on G-CSF treatment should be carefully monitored for the risk of osteopenia/osteoporosis.

Abstract
UNLABELLED Deficiency of 17β-hydroxysteroid dehydrogenase type 3 (17βHSD3), an enzyme converting androstenedione (A) to testosterone (T), is a rare cause of autosomal recessive 46,XY disorder of sexual development (DSD). A 18-years phenotypically female patient from southern Italy presented with primary amenorrhea. She had deep voice, macrocephaly, enlarged and bulbous nasal tip, macrostomia, facial acne, breast asymmetry, hypoplasia of the first finger of right hand, proximal implant of the fifth metatarsus bilaterally as well as an increased muscle mass and hirsutism, with hair distribution on face, neck, chest, abdomen, pubic region and on upper and lower limbs. Genital exam showed thickened labra majora with absence of labra minora and a blind-ending pseudo-vagina with clitoris enlargement. Karyotype analysis showed a male genotype (46,XY). Hormonal evaluation showed decreased T (188 ng/dL-6.5 nmol/L) and increased A (10 ng/mL-34,96 nmol/L), considering male reference ranges, resulting in a decreased T/A ratio (0,186). MRI identified testicles in inguinal regions. Human Chorionic Gonadotropin test showed T/A ratio permanently under 0,8. These evidences were suggestive of a 46,XY DSD due to 17βHSD3 deficiency. An homozygous mutation (IVS3 -1 G>C or c.326-1G>C) of the 17βHSD3 gene was discovered. Psychologist identified a well determined female gender identity. It was decided to proceed with gonadectomy and vaginal enlargement by use of dilatators. CONCLUSION The case described represents a new case of DSD due to 17βHSD3 deficiency. This patient, raised as a girl, is diagnosed in a very late stage. The identified mutation, previously reported only in Dutch and Brazilian population, is one of 27 presently known mutations of 17βHSD3 gene and is never reported in Italian population.

Abstract
BACKGROUND Neutropenia and/or neutrophil dysfunction are part of glycogen storage disease type 1b (GSD1b) phenotype. Recent studies indicated that activation of apoptosis and increased reactive oxygen species are implicated in the pathogenesis of neutropenia in GSD1b. METHODS We studied seven GSD1b patients over a 2-year-period to evaluate the efficacy of vitamin E, a known antioxidant, in preventing or improving the clinical manifestations associated with neutropenia and neutrophil dysfunction. Frequency and severity of infections, neutrophil counts and function, ileocolonoscopy and intestinal histology, were monitored. During the first year, patients did not assume vitamin E; during the second year of the study, vitamin E supplementation was added to their therapeutic regimens. RESULTS During vitamin E supplementation, the mean values of neutrophil counts were significantly higher (p < 0.05) and neutrophil counts lower than 500/mm(3) were found less frequently (p < 0.05); the frequency and severity of infections, mouth ulcers and perianal lesions, was reduced (p < 0.05); ileocolonoscopy and histology showed a mild improvement. Vitamin E supplementation did not result in changes in neutrophil function. CONCLUSIONS These results suggest that vitamin E supplementation might be beneficial in GSD1b patients and may alleviate disease manifestations associated with neutropenia.

Abstract
Glycogen storage disease type Ib (GSD Ib, OMIM 232220) is an inborn disorder of glucose metabolism, caused by mutations in the G6PT gene, encoding a glucose 6-phosphate transporter (G6PT). GSD Ib is mainly associated with fasting hypoglycaemia and hepatomegaly. Most GSD Ib patients also show neutropenia and neutrophil dysfunction and therefore are at risk of developing severe infections and inflammatory bowel disease (IBD). An increased risk for autoimmune disorders, such as thyroid autoimmunity and Crohn-like disease, has also been demonstrated, but no systematic study on the prevalence of autoimmune disorders in GSD Ib patients has ever been performed. We describe a 25-year-old patient affected by GSD Ib who developed 'seronegative' myasthenia gravis (MG), presenting with bilateral eyelid ptosis, diplopia, dysarthria, severe dysphagia, dyspnoea and fatigue. The repetitive stimulation of peripheral nerves test showed signs of exhaustion of neuromuscular transmission, particularly evident in the cranial area. Even in the absence of identifiable anti-acetylcholine receptor antibodies, seronegative MG is considered an autoimmune disorder and may be related to the disturbed immune function observed in GSD Ib patients.

Abstract
We describe three patients with type A Niemann-Pick disease (NPD-A). NPD-A is an autosomal recessive neuronal storage disease classified among the sphingolipidoses, characterized by accumulation of sphingomyelin in various tissues and in the brain. Magnetic Resonance imaging (MRI) of our three patients showed a marked delay of myelination with frontal atrophy. Few descriptions of this MRI pattern of delayed myelination have been published to date.

Abstract
Holt-Oram syndrome (HOS) (OMIM 142900) is characterized by upper-extremity malformations involving the radial, thenar, or carpal bones and a personal and/or family history of congenital heart defects (CHDs). It is inherited in an autosomal dominant manner. The TBX5 gene located on chromosome 12 (12q24.1) is the only gene currently known to be associated with HOS and is associated with variable phenotypes. We report on the clinical and molecular characterization of a HOS family with three affected individuals and a novel mutation (Lys88ter). We discuss genotype-phenotype correlations, the presence of foot anomalies in one affected individual, and the role of atypical features in HOS differential diagnosis.

Abstract
AIMS/HYPOTHESIS Estimated glomerular filtration rate (eGFR) predicts mortality in non-diabetic populations, but its role in people with type 2 diabetes is unknown. We assessed to what extent a reduction in eGFR in people with type 2 diabetes predicts 11-year all-cause and cardiovascular mortality, independently of AER and other cardiovascular risk factors. MATERIALS AND METHODS The study population was the population-based cohort (n = 1,538; median age 68.9 years) of the Casale Monferrato Study. GFR was estimated by the abbreviated Modification of Diet in Renal Disease Study equation. RESULTS At baseline, the prevalence of chronic kidney disease (eGFR <60 ml min(-1) 1.73 m(-2)) was 34.3% (95% CI 33.0-36.8). There were 670 deaths in 10,708 person-years of observation. Hazard ratios of 1.23 (95% CI 1.03-1.47) for all-cause mortality and 1.18 (95% CI 0.92-1.52) for cardiovascular mortality were observed after adjusting for cardiovascular risk factors and AER. When five levels of eGFR were analysed we found that most risk was conferred by eGFR 15-29 ml min(-1) 1.73 m(-2), whereas no increased risk was evident in people with eGFR values between 30 and 59 ml min(-1) 1.73 m(-2). In an analysis stratified by AER categories, a significant increasing trend in risk with decreasing eGFR was evident only in people with macroalbuminuria. CONCLUSIONS/INTERPRETATION Our study suggests that in type 2 diabetes macroalbuminuria is the main predictor of mortality, independently of both eGFR and cardiovascular risk factors, whereas eGFR provides no further information in normoalbuminuric people.

Glycogenosis type III (Cori disease) is an autosomal recessive disorder caused by the deficiency of the glycogen debranching enzyme, encoded by the AGL gene, and existing in six isoforms alternately spliced in a tissue-specific way. Generally, disease onset occurs early on starting from the first year of life, with hepatomegaly, hypoglycemia, hyperlipidemia, increased CK levels, and, in some cases, short stature and slight mental retardation. Frequently, hepatomegaly tends to resolve spontaneously and inexplicably during childhood, when myopathy, often associated with cardiomyopathy, arises. This disease is known to lack almost invariably clear links between the genotype and clinical phenotype. We describe nine new mutations in Italian patients: four nonsense (p.Arg285X, p.Lys422X, p.Arg910X, p.Arg977X), three frameshift (c.442delA, c.753_756delGACA, c.3963delG), and two missense (p.Ala1120Pro, p.Arg524His). Particularly, the nonsense p.Arg285X is linked to an exonic splicing enhancer and it was found to produce two species of transcripts at the same time. Moreover, we discuss a subgroup of subjects carrying c.2681+1G>A, which has proven to be the most frequent mutation among our patients. The previously described c.664+3A>G was also detected in two patients, both homozygous. The present work is yet another confirmation that the individual genetic background plays a pivotal role in influencing the phenotypes, as occurs in other metabolic diseases.

Abstract
BACKGROUND The efficacy of ACE-inhibitors in decreasing microalbuminuria and proteinuria has been reported in a few patients with glycogen storage disease type 1 (GSD1); however, no case-control study has ever been published. AIM The aim of the current study was to evaluate the efficacy of ACE-inhibitors in reducing glomerular hyperfiltration, microalbuminuria and proteinuria, and in delaying the progression of renal damage. PATIENTS AND METHODS Ninety-five patients (median age at the time of the study: 14.5 years) were enrolled from nine Italian referral centres for metabolic diseases. A retrospective study of a 10-year follow-up was conducted in order to compare the evolution of these parameters in treated patients with those who were not treated with ACE-inhibitors. RESULTS A significant and progressive decrease of glomerular filtration rate was observed in treated patients vs. those who were not treated with ACE-inhibitors (P < 0.05). No difference was observed for microalbuminuria and proteinuria between the two groups of patients. Moreover, the ACE-inhibitors significantly delayed the progression from glomerular hyperfiltration to microalbuminuria, but not that from microalbuminuria to proteinuria. CONCLUSIONS The results of the present study underline the importance of a strict follow-up of renal function in GSD1 patients. The detection of glomerular hyperfiltration suggests precocious initiation of ACE-inhibitor treatment to delay the progression of renal damage. A randomized prospective study is needed to establish for certain the real effectiveness of this treatment in GSD1 patients.

Abstract
Deficiency of a microsomal phosphate transporter in the liver has been suggested in some patients affected by glycogen storage disease type Ic (GSD Ic). Several Na(+)/phosphate co-transporters have been characterized as members of the anion-cation symporter family. Recently, the cDNA sequence of two phosphate transporters, NPT3 and NPT4, expressed in liver, kidney and intestine, has been determined. We studied expression of human NPT4 in COS cells and observed an ER localization of the transporter by immunofluorescence microscopy. We speculated that this transporter could play a role in the regulation of the glucose-6-phosphatase (G6-Pase) complex. We revealed the genomic structure of NPT4 and analysed the gene as a candidate for GSD Ic. DNA was collected from five patients without mutations in G6-Pase or the G6-P transporter gene. DNA analysis of NPT4 revealed that one patient was heterozygous for a G>A transition at nucleotide 601 which would result in a G201R substitution. Our results do not confirm the hypothesis that this gene is mutated in GSD Ic patients. However, we cannot exclude that the mutation found reduces the phosphate transport efficiency, possibly modulating the G6-Pase complex.

Abstract
AIM To investigate the presence of inflammatory bowel disease (IBD) and to evaluate the progression of bowel involvement after two years' follow-up in seven patients affected by glycogen storage disease type Ib (GSDIb). METHODS Seven patients (5F, 2M, aged 4.5-20.6 y) entered the study. Bowel involvement was evaluated by ileocolonoscopy and specific IBD serologic markers. To evaluate disease activity, Paediatric Crohn's Disease Activity Index (PCDAI), terminal ileum wall thickness detected at ultrasonography (US), 99mTechnetium labelled autologous White Cell Scan (Tc-WCS) and barium meal with follow-through were investigated. RESULTS Ileocolonoscopy and histology examination revealed variable degrees of bowel involvement in all patients. The results of serologic markers were indicative of a Crohn's-like ileocolitis. US and Tc-WCS, could clearly define patients with severe inflammatory involvement, but failed to identify all patients with mild to moderate disease. For the most severely affected patients, anti-inflammatory agents and steroids were prescribed, whereas nutritional therapy with polymeric formula and antibiotics were assumed by two other patients and antibiotics only by one patient. Granulocyte colony-stimulating factor (G-CSF) was prescribed to all patients. Ileocolonoscopy and histology data improved in all patients. The assumption of G-CSF and/or gastric drip feeding (g.d.f.) was inversely associated with the PCDAI results (p < 0.05). CONCLUSION IBD is common in patients affected by GSDIb independently of the severity of gastrointestinal signs and symptoms. Different therapeutic approaches can be used according to the severity of IBD. G-CSF treatment and g.d.f. can be protective factors for IBD.

Abstract
Total or partial lack of glycogen debranching enzyme (GDE or AGL, amylo-1,6-glucosidase, 4-alpha-glucanotransferase) is responsible for Glycogen Storage Disease type III (GSDIII), a rare autosomal recessive disorder of glycogen metabolism. The clinical and biochemical features of GSDIII subjects are quite heterogeneous, and this mirrors the genotype-phenotype heterogeneity among patients. In this paper, we report the molecular characterisation of five unrelated subjects, four Italian and one Tunisian. The following new mutations are described and confirm the genetic heterogeneity of this disease: p.R864X, p.R428K, c.3911 insA, p.G1087R and c.3512_3549dup+c.3512_3519del. The functional relevance of these mutations is discussed on the basis of the recently acquired knowledge about the boundaries and structures of the two catalytic domains.

Abstract
Deficiency of amylo-1,6-glucosidase, 4-alpha-glucanotransferase enzyme (AGL or glycogen debranching enzyme) is causative of Glycogen Storage Disease type III, a rare autosomal recessive disorder of glycogen metabolism. The disease has been demonstrated to show clinical and biochemical heterogeneity, reflecting the genotype-phenotype heterogeneity among different subjects. The aim of this study was the molecular characterisation of eight unrelated patients from an ethnically heterogeneous population (six Italians, one from India and another one from Tunisia). We describe six novel mutations responsible for the disease (C234R, R675W, 2547delG, T38A, W1327X, IVS6 +3 A>G) and the presence in two Italian subjects of a splice variant (IVS21(+1) G>A) already described elsewhere. This last one is confirmed to be the most frequent mutation among the Italian patients come to our observation, accounting for 28% of 21 patients. One subject was found to be a compound heterozygous. Our data confirm the substantial genetic heterogeneity of this disease. Consequently, the strategy of mutation finding based on screening of recurrent common mutations is limited, as far as regards Italian GSD III patients, to check for the presence of IVS21(+1) G>A.

Abstract
Deficiency of amylo-1,6-glucosidase, 4-alpha-glucanotransferase enzyme (AGL or glycogen debrancher enzyme) is responsible for glycogen storage disease type III, a rare autosomal recessive disorder of glycogen metabolism. The AGL gene is located on chromosome 1p21, and contains 35 exons translated in a monomeric protein product. The disease has recognized clinical and biochemical heterogeneity, reflecting the genotype-phenotype heterogeneity among different subjects. The clinical manifestations of GSD III are represented by hepatomegaly, hypoglycemia, hyperlipidemia, short stature and, in a number of subjects, cardiomyopathy and myopathy. In this article, we discuss the genotypic-phenotypic heterogeneity of GSD III by the molecular characterization of mutations responsible for the disease on a collection of 18 independent alleles from the Mediterranean area. We identified by heteroduplex band shift, DNA direct sequencing, and restriction analysis, seven novel mutations (four nonsense point-mutations: R34X, S530X, R1218X, W1398X; two microinsertions: 1072insT and 4724insAA; and one bp deletion: 676DeltaG), together with two new cases carrying a IVS21 + 1 G --> A splicing site mutation previously described in Italian patients. Altogether, 15 alleles were characterized. The correlation between type of mutation and clinical severity was studied in six patients in whom both mutated alleles were detected. Our data confirm the extreme genetic heterogeneity of this disease, thus precluding a strategy of mutation finding based on screening of recurrent common mutations.

Abstract
Although the hypercortisolism-induced impairment of protein homeostasis is object of several studies, a detailed evaluation of the complete amino acid profile of patients with Cushing's syndrome (CS) has never been performed. The aim of the current open transversal controlled study was to evaluate serum and urinary concentrations as well as renal clearance of the complete series of natural amino acids and their relationship with glucose tolerance in patients with Cushing's disease (CD). Twenty patients with CD (10 active and 10 cured) and 20 sex- and age-matched healthy controls entered the study. Measurement of serum and urinary levels of the complete series of natural amino acids was performed in all patients analyzed by cationic exchange high performance liquid cromatography (HPLC) after 2 weeks of a standardized protein intake regimen. The renal clearance (renal excretion rate) of each amino acid was calculated on the basis of the serum and urinary concentrations of creatinine and the specific amino acid. Fasting glucose and insulin levels, glucose and insulin response to standard glucose load, insulinogenic and homeostasis model insulin resistance (Homa-R) indexes were also evaluated and correlated to the circulating levels and renal clearances of each amino acid. Significantly higher serum (p<0.01) and urinary (p<0.05) levels of alanine and cystine, lower serum and higher urinary levels of leucine, isoleucine and valine (p<0.05) and higher renal excretion rates of leucine, isoleucine and valine (p<0.01) were found in patients with active CD than in patients cured from the disease and in controls. No difference was found between cured patients and controls. Creatinine clearance was similar in active and cured patients and in controls. In patients with active CD, urinary cortisol levels were significantly correlated to urinary cystine levels (r=0.85; p<0.01) and renal excretion rate of leucine (r=-0.76; p<0.05), isoleucine (r=-0.76; p<0.05) and valine (r=-0.66; p<0.05). Fasting blood glucose levels were significantly correlated to serum alanine levels (r=0.70; p<0.05). Although Homa-R was significantly correlated to BMI in active patients (r=0.74 p<0.05), it was not correlated to amino acid levels. In conclusion, the results of the current study demonstrate that patients with CD have significant changes in serum and urinary concentration of several amino acids and changes in renal clearance of some specific amino acids. Normalization of cortisol levels restored the amino acid profile.

Abstract
Glycogen storage diseases type 1 (GSD 1) are a group of autosomal recessive disorders characterized by impairment of terminal steps of glycogenolysis and gluconeogenesis. Mutations of the glucose-6-phosphatase gene are responsible for the most frequent form of GSD 1, the subtype 1a, while mutations of the glucose-6-phosphate transporter gene (G6PT) have recently been shown to cause the non 1a forms of GSD, namely the 1b and 1c subtypes. Here, we report on the analysis by single-stranded conformation polymorphism (SSCP) and/or DNA sequencing of the exons of the G6PT in 14 patients diagnosed either as affected by the GSD 1b or 1c subtypes. Mutations in the G6PT gene were found in all patients. Four of the detected mutations were novel mutations, while the others were previously described. Our results confirm that the GSD 1b and 1c forms are due to mutations in the same gene, i.e. the G6PT gene. We also show that the same kind of mutation can be associated or not with evident clinical complications such as neutrophil impairment. Since no correlation between the type and position of the mutation and the severity of the disease was found, other unknown factors may cause the expression of symptoms, such as neutropenia, which dramatically influence the severity of the disease.

Abstract
We report on a 21 month old child referred to us because of facial dysmorphism and psychomotor retardation. The patient's phenotype was characterised by a wide and receding forehead, broad nasal bridge, redundant retronuchal skin, low set and poorly shaped ears, micrognathia, and small hands and feet. High resolution R and G banding karyotype analysis of peripheral blood lymphocytes showed an interstitial deletion of the long arm of chromosome 1 spanning bands q22 to q24. The cytogenetic results were confirmed by molecular analysis. The phenotype observed in our patient was relatively milder than those reported in other patients with an interstitial deletion of chromosome 1q.
