A familial unbalanced subtelomeric translocation resulting in monosomy 6q27-->qter.
Subtelomeric rearrangements have recently gained considerable interest through publications indicating that they may be a major cause for unexplained mental retardation and/or multiple congenital anomalies. 2 As the subtelomeric regions have the highest gene density in the genome, subtelomeric aneusomies are in general thought to have a significant effect on the phenotype. Prenatal onset of gro...
متن کاملPartial trisomy 13q22-->qter and monosomy 18q21-->qter as a result of familial translocation.
We report on a patient with a partial trisomy of chromosome 13q22-->qter and partial monosomy of chromosome 18q21-->qter showing distinct malformations. The phenotype of this unbalanced karyotype has not been previously described. The proband had a craniofacial dysmorphism, neck pterygium, closed fists with overlapping fingers, cutaneous appendix of the left fist, equinovarus and postaxial hexa...
متن کاملFamilial 4;18 chromosome translocation resulting in trisomy 4p and monosomy 18p: affected individuals with discordant phenotype.
Balanced chromosome translocations in either parent increase the risk of recurrent miscarriage, unbalanced chromosome rearrangements, congenital malformations, and mental retardation in liveborn offspring. Chromosome aberrations account for at least 50% of fetal losses prior to 15 weeks’ estimated gestation (EGA). Of these, 60% occur secondary to autosomal trisomies (Gardner and Sutherland, 200...
متن کاملPartial trisomy 2q(2q37.3-->qter) and monosomy 7q(7q34--->qter) due to paternal reciprocal translocation 2;7: a case report.
We report an unbalanced translocation involving chromosome 2 and 7 due to a balanced reciprocal translocation 2;7 in the father. The female fetus had a partial trisomy of the long arm of chromosome 2 with a partial monosomy of distal 7q. Ultrasound at the first trimester had indicated normal fetal anatomy, including normal intracranial structures. Parental karyotypes showed a paternal balanced ...
متن کاملMonosomy 13q32.3----qter: report of two cases.
Two unrelated patients with monosomy 13q32.3----qter are reported. Comparison with six similar cases previously published indicates that the craniofacial dysmorphism of the 13qter monosomy syndrome is related to band 13q34, the thumb hypoplasia to band 13q32, and an apparently different phenotype to band 13q33. Coagulation deficiency appears to be non-specific in monosomy 13qter.
