[PMID: 25648949 PMCID: PMC4314806 DOI: 10.1186/s13039-014-0101-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2014] [Accepted: 12/12/2014] [Indexed: 11/10/2022] Open
Abstract
11qter trisomy is rare, mostly occurs in combination with partial monosomy of a terminal segment of another chromosome due to unbalanced segregation of parental translocations. Pure 11qter trisomy is rarer, only five cases have so far been reported. Here we report a family with all four siblings affected with neurodevelopmental disorders and facial dysmorphism. Chromosomal microarray analysis (CMA) identified 11q23.3-qter (15.1 Mb) deletion in one and reciprocal duplication in the other three siblings. Both father and grandfather are balanced translocation (46, XY, t (10;11) (q26;q23)) carriers. The genetic material involved on chromosome 10 is very limited (270 kb). Thus, the pedigree presented rare cases with "pure" 11qter trisomy or reciprocal 11qter monosomy (Jacobsen syndrome), offering a unique opportunity to examine clinical presentations of multiple individuals with identical genomic imbalance. The proband with 11qter monosomy presented with many features of Jacobsen syndrome. The three 11qter trisomy carriers presented with shared craniofacial features including brachycephaly and short philtrum. They are also significant for the following neurodevelopmental and neuropsychiatric defects: intellectual disability, expressive language deficiency, autistic features, auditory hallucination, self-talking and pain insensitivity. To our knowledge, this is the smallest "pure" trisomy 11qter so far reported and this is the first report to describe the neuropsychiatric features of patients with 11qter trisomy. Our observation also revealed dissimilar features in our patients compared with those of previously published trisomy 11qter cases. The pedigree also revealed phenotypic heterogeneity among siblings with identical genomic imbalance.

Recurrence risks for different pregnancy outcomes and meiotic segregation analysis of spermatozoa in carriers of t(1;11)(p36.22;q12.2). J Hum Genet 2014; 59:667-74. [PMID: 25319850 DOI: 10.1038/jhg.2014.92] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2014] [Revised: 09/16/2014] [Accepted: 09/18/2014] [Indexed: 01/16/2023]
Abstract
Cumulative data obtained from two relatively large pedigrees of a unique reciprocal chromosomal translocation (RCT) t(1;11)(p36.22;q12.2) ascertained by three miscarriages (pedigree 1) and the birth of newborn with hydrocephalus and myelomeningocele (pedigree 2) were used to estimate recurrence risks for different pregnancy outcomes. Submicroscopic molecular characterization by fluorescent in situ hybridization (FISH) of RCT break points in representative carriers showed similar rearrangements in both families. Meiotic segregation patterns after sperm analysis by three-color FISH of one male carrier showed all possible outcomes resulting from 2:2 and 3:1 segregations. On the basis of empirical survival data, we suggest that only one form of chromosome imbalance resulting in monosomy 1p36.22→pter with trisomy 11q12.2→qter may be observed in progeny at birth. Segregation analysis of these pedigrees was performed by the indirect method of Stengel-Rutkowski and showed that probability rate for malformed child at birth due to an unbalanced karyotype was 3/48 (6.2±3.5%) after ascertainment correction. The risk for stillbirths/early neonatal deaths was -/48 (<1.1%) and for miscarriages was 17/48 (35.4±6.9%). However, the probability rate for children with a normal phenotype at birth was 28/48 (58.3±7.1%). The results obtained from this study may be used to determine the risks for the various pregnancy outcomes for carriers of t(1;11)(p36.22;q12.2) and can be used for genetic counseling of carriers of this rearrangement.

Combined partial trisomy 11q and partial monosomy 10p in a 19-year-old female patient: phenotypic and genotypic findings. Am J Med Genet A 2011; 155A:3075-81. [PMID: 22052712 DOI: 10.1002/ajmg.a.34300] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2010] [Accepted: 07/31/2011] [Indexed: 11/08/2022]
Abstract
Constitutional partial trisomy 11q in man mostly occurs in combination with partial trisomy 22 due to a balanced parental translocation t(11;22). Occasionally a chromosome other than 22 is involved in the parental translocation with chromosome 11, resulting in partial monosomy for the other participating chromosome. We report of a patient with partial trisomy 11q and partial monosomy 10p [46,XX,der(10)t(10;11)(p15;q22)] due to a paternal balanced translocation [46,XY,t(10;11)(p15;q22)]. Array CGH showed heterozygosity for a deletion of ∼3.46 Mb at 10p15.3p15.2 and gain of ∼32.21 Mb at 11q22.2q25. The patient, a 19-year-old woman, has a multiple congenital anomaly syndrome with severe developmental and growth delay, muscular hypotonia, iris coloboma, abnormal external ears, widely spaced nipples, atrial septum defect, clubfoot, and arthrogryposis multiplex congenita. Despite multiple health problems and numerous hospitalizations due to massive seizures, pulmonary insufficiency and recurrent infections the patient reached adulthood. The clinical features in our patient are compared to other cases reported in the literature of either partial monosomy 10p or partial trisomy 11q. To the best of our knowledge, this is the first report of the combination of partial trisomy 11q and partial monosomy 10p. Comparing the molecular karyotype and the phenotype of our patient to other patients, the clinical features of our patient are more likely due to partial trisomy 11q than to partial monosomy 10p.
