Abstract
PURPOSE To report two new cases with confirmed diagnosis of Heimler syndrome and describe their systemic and ophthalmic phenotype and visual rehabilitation. METHODS Retrospective review of medical records. RESULTS Both siblings were diagnosed as having sensori-neural hearing loss and retinal dystrophy with exuberant intraretinal cystoid spaces and cone-rod dysfunction. The older sibling also had amelogenesis imperfecta and neither had nail abnormalities. Genetic analysis identified homozygosity for the pathogenic variant c.2528G>A p.(Gly843Asp) in the PEX1 gene in both siblings. The parents were heterozygous carriers of the variant. CONCLUSIONS The authors report a familial case of Heimler syndrome due to biallelic PEX1 pathogenic variants that manifested as macular dystrophy characterized by cone-rod dysfunction and complicated by intraretinal cystoid spaces. Review of the literature shows that ocular phenotype is variable in patients with Heimler syndrome. [J Pediatr Ophthalmol Strabismus. 2024;61(1):59-66.].

Abstract
FLOTCH (leukonychia totalis-trichilemmal cysts-ciliary dystrophy syndrome) syndrome is a rare genetic cutaneous disorder primarily characterized by multiple recurrent trichilemmal pilar cysts and leukonychia. It may be associated with ciliary dystrophy, koilonychia, and/or less frequently renal calculi and pancreatitis inherited in an autosomal-dominant fashion. We report the case of a 25-year-old Black woman who presented with white-colored fingernails and enlarging cysts in multiple locations including the scalp, rib cage, and forearm and was diagnosed with suspected FLOTCH syndrome. Pilar cysts in unusual locations along with distinct nail changes should prompt clinicians to consider further investigation for conditions such as FLOTCH syndrome.

Abstract
DOOR syndrome is an extremely rare genetic disorder. "DOOR″ is an acronym to describe the combination of: deafness, onychodystrophy, osteodystrophy and mental retardation. We present a patient, with all of the above-mentioned main symptoms, that was rehabilitated with convencional hearing aids. The presented case suggested that every case of deafness and abnormal nails and phalanges in the hands and feet should have a clinical diagnosis of possible DOOR syndrome. Based on embryological process, congenital abnormal nails or phalanges highlights the importance for detailed hearing screening.

Abstract
Elastomas are connective tissue nevi or hamartomas. They may occur in isolation or can be associated with familial syndromes such as Buschke-Ollendorff syndrome. Elastomas typically present in childhood as small ivory papules or firm skin-colored nodules that can coalesce into larger yellow plaques. These lesions are typically distributed over the extremities, abdomen, and back. Herein, we report an unusual case of a renal transplant recipient who presented with an acquired subungual papule with associated koilonychia and distal nail plate dystrophy. Histopathologic findings were consistent with subungual elastoma.

Abstract
IMPORTANCE Dyskeratosis congenita is a rare disorder that often leads to early death owing to a variety of complications and associated disorders. Early diagnosis and intervention is important in care for patients affected by this disease. OBSERVATIONS We describe a patient with dyskeratosis congenita (DC) in a child. Our patient had a 3-year history of transaminitis that was felt to be the result of biopsy proven progressive fibrosis of the liver beginning at age 3. He was referred to the dermatology department because of a chronic, evolving eruption with the hope of establishing a unifying diagnosis. Further examination revealed dystrophic nails, numerous dental caries, and blepharitis. Chromosomal analysis on leukocytes showed significant telomere shortening consistent with DC. CONCLUSIONS AND RELEVANCE Early recognition and long term care is important in patients with DC because of their propensity to develop malignancy, hematologic abnormalities, and infection. Better understanding of this disease may lead to insights into other disorders associated with abnormal telomere maintenance.

Abstract
Bart's syndrome, first described by Bart in 1966, consists of congenital localized absence of skin, congenital epidermolysis bullosa, and associated nail abnormalities. A newborn infant with Bart's syndrome is reported since it is a very rare condition, especially when associated with pyloric and concomitant choanal atresia. To the best of our knowledge, this is the first report presenting a case of Bart's syndrome associated with choanal atresia.

Abstract
We present the case of a newborn with congenital absence of skin in the anterior part of the left leg that shortly after developed bulla and erosions in hands, feet, ears, buttocks and mouth. The cutaneous biopsy and ultrastructural and immunohistochemical studies showed a subepidermal bulla in the lamina lucida, absence of hemidesmosomes and marked decrease of laminin 5, thus establishing the diagnosis of Bart syndrome associated to the Herlitz form of lethal junctional epidermolysis bullosa. Bart syndrome consists of congenital and localized absence of skin, nail abnormalities and mucoc-cutaneous bullae. It is usually associated to dystrophic epidermolysis bullosa. The Herlitz form of junctional epidermolysis bullosa is a rare variant, usually lethal that is produced by mutations in the genes coding for the anchor protein laminin 5. To our knowledge this is the second case that reports an association between Bart syndrome and lethal junctional epidermolysis bullosa and the first in which the results of immunofluorescence mapping are published.

Abstract
Psoriasis is a widespread skin disorder in which nail involvement can be seen in up to two-thirds of those affected. Childhood psoriasis is a distinct entity and the literature focused on nail changes associated with childhood psoriasis is scant. Our objectives were to evaluate the frequency of nail involvement in childhood psoriatic patients, assess the types of nail changes in childhood psoriasis, and compare our clinical findings with the few reports available in the literature. Two hundred and one consecutive new patients with childhood (age < or = 16 years) psoriasis of both sexes were selected for the study of nail changes. The diagnosis of psoriasis was made on clinical grounds. Each patient underwent a thorough dermatologic examination with special attention paid to the nail changes. If a clinical suspicion of fungal infection of the nails existed, further mycologic investigations were performed. We found the prevalence of nail changes to be 37.81% (boys > girls) in children who had psoriasis. Nail pitting was found to be the most common manifestation (61.84%) followed by onycholysis (30.26%), subungual hyperkeratosis (13.16%), and discoloration of the nail plate (7.90%). Nail involvement had no relationship to the type of psoriasis, patient's sex, or duration or extent of disease.

Abstract
BACKGROUND Transverse overcurvature of the nail is a painful condition that has been treated by conservative and/or surgical methods. OBJECTIVES We sought to evaluate the efficacy of a plastic device for treatment of transverse overcurvature of the nail and to use a practical method (plaster mold) to evaluate follow-up of nail widening during and after treatment. METHODS Twenty-five patients with transverse overcurvature of the nail were treated with placement of a plastic device. Pain assessment was done on a monthly basis. Nail improvement was evaluated through photographs and measurement of widening by plaster molds. RESULTS Relief of pain could be determined in almost 100% of the cases in a 3-month period. Widening of overcurvature of the nail occurred in all cases. The plaster mold allowed a practical measurement of improvement in nail shape. CONCLUSION The plastic device is an effective, safe, noninvasive, and inexpensive treatment option for overcurved nails. The plaster mold is a practical method to evaluate improvement in nail shape.

Abstract
Systemic disease can produce changes in the nails. Perhaps the best known example of this is koilonychia as a sequale of iron deficiency anemia. "Half and half nail" is a type of pseudoleuconychia that can be caused by chronic renal disease, Kawasaki's disease, cirrhosis, and zinc deficiency. It has not been described in patients with Crohn's disease yet. Four male patients with Crohn's disease were observed. None of them had extraintestinal manifestations of Crohn's disease. The average duration of the disease was 5.25 (range, 1-10) years. The nail alterations were defined with a portion of the nail being as much as 15 to 40 percent of normal color distally, whereas the rest of the nail was white. The contrast between the two zones remains sharply demarcated even after constricting venous return. Histologic examination was not performed. Every patient had zinc deficiency but not hypalbuminaemia or sideropenia. After review of relevant literature (MEDLINE, PubMed, etc.), we found that half-and-half nail had not been described in Crohn's disease. This study was designed to highlight the fact that the half-and-half nail, which was thought to be a sign of chronic renal failure, also occurs in patients with Crohn's disease. The relationship of this symptom to clinical activity cannot yet be assessed and has only been observed in four cases.

Abstract
Psoriatic arthritis was described as a distinct rheumatic disease in the 1960s, and subsequently grouped among the spondyloarthropathies. Recently, other rheumatic manifestations of psoriasis, such as enthesopathy and osteoperiostitis, were recognized. This study attempts to examine the rheumatological and radiological manifestations of Psoriasis and their association with skin and nail disease. Eighty-one psoriatic outpatients were interviewed consecutively during 6 months. Questionnaires and indices were carried out to assess the extent and severity of skin and nail involvement, as well as the activity and severity of peripheral and axial rheumatic manifestations. Radiological examination of the hands, feet, spine and pelvis was also done for all patients. Fifty-nine psoriatic outpatients (73%) had rheumatic manifestations clinically and/or radiologically (Psoriatic arthropathy "PsA"). Clinical peripheral arthritis was found in 14 (23.7%) of the patients with PsA, being oligoarticular in 11, polyarticular in two, and exclusively of the distal interphalangeal (DIP) joints in one patient. Sacroiliitis and/or spondylitis were found in 38 (64.4%), enthesopathy in 36 (61%), dactylitis in two (3.3%), radiological DIP involvement in 24 (40.6%), and radiological osteoperiostitis in 49 (83%) of patients with PsA. Most PsA patients had more than one rheumatic manifestation, while four patients (6.7%) had isolated enthesopathy without any other rheumatic manifestations. Subungual hyperkeratosis of the nails was significantly correlated with PsA (p<0.05), as well as with clinical arthritis, enthesopathy, and DIP involvement (p<0.01), while other types of skin and nail lesions were correlated with selected rheumatic manifestations. The performance of existing criteria for PsA was poor, as individual sets favored either sensitivity or specificity. Psoriatic arthropathy (PsA), occurring in about three-quarters of hospital outpatients with psoriasis, is more common than previously thought. More sensitive and specific criteria for the diagnosis and classification of PsA need to be developed, taking into account the recently described clinical and radiological manifestations.

Abstract
Rubinstein-Taybi syndrome (RTS) is a well-known disorder characterized by growth and mental retardation, typical facial features, short stature, and broad thumbs and toes. Although several cutaneous manifestations are observed in these patients, they are not diagnostic and are usually considered to be coincidental. Congenital malalignment of the great toenails is a very rare disorder that is characterized by lateral deviation of the nail plate along its longitudinal axis. The nail plate grows into the lateral nail fold resulting in pain and infection. It is usually present at birth or begins in early childhood. We report a patient with characteristic manifestations of RTS and congenital malalignment of the great toenails. The association of these two entities has not been reported previously.

Abstract
BACKGROUND Pachyonychia congenita (PC) is a group of autosomal dominant ectodermal dysplasias caused by mutations in four differentiation-specific keratin genes. Two major clinical subtypes of PC have been generally recognized. Symmetrically thickened fingernails and toenails are the defining characteristic of PC type 2 (PC-2) with onset at infancy. Pilosebaceous cysts are the best hallmark of PC-2, but they usually occur at puberty. OBJECTIVES To report a Chinese pedigree of PC-2 with unusually early onset sebaceous cysts and to explore the genetic mutation and its phenotype. METHODS Exon 1 of keratin 17 was amplified by polymerase chain reaction (PCR) from genomic DNA from the three patients in the pedigree, the proband, his half-sister and his younger son, two unaffected members in the pedigree and 50 unrelated and unaffected people. PCR products were directly sequenced to detect the mutation. RESULTS Direct sequencing of the PCR products revealed a heterozygous 275A-->G mutation in all three affected members. This mutation predicts the substitution of asparagine by serine in codon 92 (N92S) located in the 1A domain of keratin 17. CONCLUSIONS Mutation in the 1A domain of keratin 17 underlies the affected members' phenotype, PC-2 with early onset sebaceous cysts and late-onset thickened fingernails and toenails. The onset of the cysts is very early in some people within this family and the age at onset of thickened fingernails and toenails is variable within the family, implying the existence of modifying factors.

Abstract
OBJECTIVE To present the otolaryngologic manifestations and management of 12 patients with the rare presentation of ectodermal dysplasia. STUDY DESIGN A retrospective chart review combined with a patient evaluation by the specialties of genetics, dermatology, dentistry, and otolaryngology. METHODS A review of the head and neck manifestations of the spectrum ectodermal dysplasia was undertaken by a retrospective chart review performed at a tertiary care children's hospital combined with a multidisciplinary evaluation by specialties of genetics, dermatology, dentistry, and otolaryngology. RESULTS All 12 patients had confirmed ectodermal dysplasia by genetic evaluation with strong familial manifestations of the spectrum. Seven of 12 patients presented with X-linked hypohidrotic ectodermal dysplasia. Three of these seven were femalepatients and presented with variable expression. Common otolaryngologic manifestations included eczematoid skin changes, unusual facies, hypodontia, sparse scalp hair, chronic infections (rhinitis, pharyngitis, otitis media), epistaxis, ocular drying with corneal injury, dysphagia, hearing loss, and dysphonia. Immune evaluation was normal. Nasal cilia were deficient. CONCLUSIONS Ectodermal dysplasia is a rare syndrome with heterogeneous manifestations secondary to hypoplasia of the mucous glands of the upper aerodigestive tract and ectodermal abnormalities. The spectrum is marked byhypohidrosis, recurrent ocular infections, chronic rhinitis, hypodontia, dystrophic nails, alopecia, and atypical facies. The recognition of this syndrome allows early management of ocular, dental, infectious, and dermatologic concerns with a multidisciplinary approach to management. Direct otolaryngologic management includes ocular and oral lubrication, treatment of infectious complications, and intervention to prevent and address hearing loss.

Abstract
Skin and nail lesions are very rare in Marfan's syndrome. We reported a 14-year-old boy who presented with pterygium in the nails of both the upper and lower limbs with chest deformity along with other features of Marfan's syndrome. Histopathological findings revealed hyperkeratosis with a scant perivascular inflammatory infiltrate. It was not clear whether this case is the first presentation of pterigium in Marfan's syndrome or congenital lichen planus. To our knowledge, this kind of feature is the first Marfan's syndrome case of its kind.

Abstract
Congenital extreme insulin resistance syndrome has rarely been reported in Taiwan. In 1982, a girl of a consanguineous marriage was noted to have increased body hair, an enlarged clitoris, and acanthosis nigricans at birth. Two months later, she received an operation for bilateral polycystic evaries. She was found to have diabetes at 8 years old and was treated with insulin. In March 1999, she was referred to our clinic with growth retardation and poor glycemic control. She had a characteristic face with a saddle nose, broad mouth, large low-set ears, absence of subcutaneous fat, and deformed nails. Although a very high dose of insulin (> 10 IU/kg/day) was used, her glycemic control was very poor (HbA1c 13.8%). Pediatricians should remain alert for the manifestations of extreme insulin resistance.

A rare association of twenty-nail dystrophy with segmental vitiligo is described in two patients. Vitiligo preceded the nail dystrophy. In both cases, all twenty nails were uniformly affected with the nail plates showing longitudinal striations and loss of luster. Longitudinal nail biopsy revealed a histological picture suggestive of eczematous changes and lichen planus respectively. Intramatrix injections of triamcinolone acetonide into the proximal and lateral nail folds were administered with considerable improvement.

Abstract
Congenital hypertrophy of the nail folds of the hallux describes an abnormality of the periungual soft tissues of the big toe characterized by hypertrophy of the nail fold which partially covers the nail plate and is frequently associated with inflammation and pain due to an ingrowing nail. We describe the clinical picture and follow-up of seven patients with this abnormality. In three patients the affected toe showed an asymptomatic, dome-shaped, hypertrophic lip that partially covered the nail plate. Four patients had acute inflammatory changes due to toenail ingrowth, with considerable swelling and reddening of the hypertrophic lip that was painful on pressure. Topical treatment with steroids was useful to reduce inflammation and produced persistent remission in two patients. Follow-up showed a spontaneous disappearance of the hypertrophic nail fold in one of the seven patients. In two patients the hypertrophic lip partially regressed, but remained clearly visible, while in two patients it remained unchanged. In two patients surgical correction of the soft tissue abnormality was necessary due to painful nail ingrowth unresponsive to topical treatment.

Abstract
Toxic epidermal necrolysis (TEN) is a severe form of erythema multiforme that results in extensive epidermal sloughing; the condition is associated with a mortality of up to 70%. From 1991 to 1998, 10 children with severe toxic epidermal necrolysis were referred to a regional pediatric burn facility. Wounds were managed with strategy involving prevention of wound desiccation and superinfection, including the frequent use of biologic wound coverings. Children unable to guard their airway because of extensive oropharyngeal involvement were prophylactically intubated. Enteral nutrition was stressed. Steroids were not used and antibiotics were administered to managed specific foci of infection only. The 2 boys and 8 girls had an average age of 7.2+/-1.8 years (range 6 months to 15 years) and sloughed surface area of 76+/-6% of the body surface (range 50 to 95%). Antibiotics (3 children), anticonvulsants (3 children), nonsteroidals (2 children), and viral syndrome or unknown agents (2 children) were felt to have triggered the syndrome. Six children (60%) required intubation for an average of 9.7+/-1.8 days (range 2 to 14 days). Buccal mucosal involvement occurred in 9 (90%) and ocular involvement in 9 (90%). Although infectious complications were common (2 pneumonias, 2 urinary infections, 1 bacteremia, 2 central line infections, and 2 candidemias), all children survived after lengths of stay in the burn unit averaging 19+/-3 (range 6 to 40) days. The most common long-term morbidity was keratitis sicca (2 children, 20%), finger nail deformities (3 children, 30%), and variegated skin pigment changes (5 children, 50%). Although having both a cutaneous and visceral wound that predispose them to infectious complications, most children with TEN will survive if managed with a strategy emphasizing biologic wound closure, intensive nutritional support, and early detection and treatment of septic foci. Burn units have the resource set required to manage severe TEN and early referral of such children may have a favorable impact on survival.

Abstract
Pachyonchia congenita (PC) is an uncommon autosomal dominant genodermatosis affecting the nails and other ectodermal tissues. The most striking features are symmetrically thickened dysmorphic nails and hyperkeratotic skin lesions. We report a case of pachyonychia congenita in a 30-year-old male patient who had thickening and gray-brown discoloration of all nails and many nodules on his back and neck. He also had hyperkeratotic skin lesions on both feet. His tongue had irregularly-shaped, whitish plaques. Histology of these nodules revealed the characteristic features of steatocystoma multiplex. After treatment with oral retinoic acid, his hyperkeratotic skin lesions improved.

Abstract
The term twenty-nail dystrophy (TND) of childhood has evolved since its initial description in 1977. TND has also been reported in adults, and many clinical as well as histopathologic associations have been described. We describe the third case of a rare association of TND with vitiligo in a 10-year-old girl.

Abstract
We report on a female newborn, the youngest patient with Zimmermann-Laband syndrome hitherto reported. She had gingival hyperplasia, bulbous soft nose and ears, hypoplastic toenails, and hyperextensibility of the joints, as well as deep palmar and plantar creases, a sign not previously described in literature.

Abstract
A 6-year-old girl with epidermolysis bullosa simplex (EBS) is described. Clinical features include generalized herpetiform blistering of the skin, healing without scars, intraoral blistering, nail dystrophy, palmoplantar keratoderma, and improvement with age. An unusual feature was the presence of a striking mottled pigmentation involving the arms, trunk, and legs. Histology, immunofluorescence, and electron microscopy of a fresh lesion showed an intraepidermal split within the basal keratinocytes, focal hyperpigmentation of the basal cells without an inflammatory infiltrate, and tonofilament clumping. Our patient illustrates the clinical features of Dowling-Meara EBS with the pigmentary changes of EBS with mottled pigmentation. The relationship between EBS of Dowling-Meara and EBS with mottled pigmentation is discussed.

Abstract
'Hereditary painful callosities' defines an autosomal dominant nummular palmoplantar keratoderma characterized by the development of painful keratotic lesions over pressure points. Two unrelated patients with hereditary painful callosities with other familial acral abnormalities are reported. To our knowledge subtotal congenital leukonychia and symmetrical bone duplication of great toes have not been previously described in association with this disorder.

Abstract
Over a period of six months a 41-year-old woman had recurrent acute paronychia of both large toes. On inspection all toes had pincer nails. She had no metabolic abnormalities and no history of trauma. Onychomykosis was excluded. Under conduction anaesthesia an Emmert plasty (Haneke's modification) was performed: it revealed osteocartilaginous exostoses in the area of nail gryposis. Subsequent radiological examination showed distally directed exostoses on the tibial side of all toe phalanges, which is an obligatory criterion for the hereditary form of the pincer nail syndrome.

Abstract
Dolichonychia is a descriptive term for elongated, slender nails. Although published observations of this finding are uncommon, dolichonychia has previously been seen in patients with connective tissue disorders, with hypohidrotic ectoderma dysplasia, or with abnormal hormonal states. Dolichonychia is a clinical feature which may be observed in patients with the Marfan syndrome. A woman with the Marfan syndrome and dolichonychia is described. Measurements of the patient's arm span, height, lower segment, hand length, and middle finger length were performed. In addition, the length-to-width ratio of each of her finger nails was determined. The mean of finger nail length-to-width quotients in the patient with the Marfan syndrome was 1.54. In conclusion, the detection of dolichonychia should prompt the physician to rule out associated systemic conditions: after eunuchoidism, hypohidrotic ectodermal dysplasia, and hypopituitarism have been excluded, an evaluation for Ehlers-Danlos syndrome and the Marfan syndrome should be considered.

Abstract
Two patients suffering from pemphigus vulgaris were found to have nail dystrophies which antedated the onset of mucocutaneous lesions by many years. The nail changes improved substantially on treatment of the bullous disease. One patient had nail matrix histology consistent with pemphigus, and both had positive direct immunofluorescence with intercellular IgG in the matrix epithelium, as well as at other body sites. We propose that dystrophic nails, as a non-specific indicator of autoimmune disease, are a genuine and relevant finding in pemphigus.

Abstract
Dyskeratosis congenita is a congenital multisystem disorder, characterized by skin pigmentation, dystrophic nails, and leukoplakia. Hematologic abnormalities progressing to severe pancytopenia play a significant role in the poor prognosis of afflicted patients. We report on a patient with dyskeratosis congenita and severe aplastic anemia, complicated by life threatening infection. The patient was treated with recombinant granulocyte-macrophage colony-stimulating factor. This therapy resulted in a moderate and transient improvement in absolute neutrophil counts. Current concepts regarding the pathogenesis and etiology of dyskeratosis congenita are discussed, while reviewing the available therapeutic options.

Abstract
We report the case of a 54-year-old female who was found to have adenocarcinoma of the gall bladder 2 years after the onset of yellow discolouration and deformity of all 20 nails. She also exhibited a past history of chronic sinusitis and mild bronchiectasis. As the tumour was inoperable, palliative surgery was performed. This case adds further support to a possible association between malignancy and the yellow nail syndrome (YNS).

Abstract
A family is described in which five of the six members with the Jackson-Lawler type of pachyonychia congenita also had varying degrees of hidradenitis suppurativa. We suggest an association between this type of pachyonychia congenita and hidradenitis suppurativa.

Abstract
We report on two cases of pachyonychia congenita, Jadassohn-Lewandowsky type, in a father and daughter. Histopathological examination revealed thickened, aggregated bundles of tonofilaments and an increased number of atypical keratohyalin granula, which is suggestive of an altered keratinization. Immunohistological staining with antibodies to cytokeratins (A45-B/B3, A51-B/H4, A53-B/A2, RPN 1161) was unchanged. Filaggrin could not be detected. Basal cells immunoreactive for calmodulin were markedly reduced or even absent in the rete ridges. Staining with a monoclonal antibody against Ki67 made epidermal cell hyperproliferation seem unlikely. The epidermal lectin binding was normal. C3 was detectable in vessel walls mainly of the stratum reticulare. The findings are discussed with reference to pachyonychia pathogenesis.

Abstract
Eight cases of subungual epidermoid cysts associated with distinctive nail abnormalities are reported. Toes and thumbs were the most frequent sites affected by this probably not rare condition. The most striking clinical features were subungual hyperkeratosis associated with shortened and dystrophic nail plate. A history of trauma was frequent. In all cases, the nail biopsy showed marked hyperplasia of the nail bed and epidermoid cysts in the dermis. The authors propose a new classification for subungual epidermoid cysts.

Abstract
We report a patient with nail and bone disorders of the index and middle fingers (Iso and Kikuchi syndrome) associated with chronic discoid lupus erythematosus. Angiographic studies showed filiform arteries of the fingers and slow blood circulation. Since a vascular pathogenic mechanisms is probable, the designation "Congenital ischemic onychodystrophy" seems more suitable. The association with chronic discoid lupus erythematosus has not previously been reported.

Abstract
Triphalangeal thumb (TPT), a rare malformation of uncertain pathogenesis, may occur as an isolated defect, in association with other malformations of the hands, or as a feature of a syndrome or sequence. Isolated TPT occurs in two functional types: opposable and non-opposable. The latter appears to be inherited as a simple autosomal dominant trait, while the former is generally sporadic. TPT is associated with a number of specific malformations of the hand or foot, several of which have a well documented autosomal dominant pattern of inheritance. TPT is a feature of a number of specific syndromes. In this setting it may be associated with radial hypoplasia, bone marrow dysfunction, congenital heart disease, lung hypoplasia or agenesis, anorectal malformations, sensorineural hearing loss, onychodystrophy, mental retardation, and other disorders. TPT serves as a useful marker in such patients; in conjunction with the clinical and radiological findings, it can help to establish the correct diagnosis, leading to appropriate management and genetic counselling.
