We report on a Japanese boy with interstitial deletion of chromosome 12q12-q13.12, who had multiple congenital anomalies with severe psychomotor retardation. Most of the clinical manifestations were compatible with Noonan syndrome phenotype except for the absence of cardiac defects. Severe mental re

β¦ Synopsis
We present the clinical, cytogenetic, and molecular studies on a constitutional deletion of 19q ascertained prenatally due to decreased fetal activity and IUGR. Chromosome analysis by GTG banding on amniocytes suggested a del(19)(q13.1q13.3), but the analysis of microsatellites by PCR demonstrated that the deletion involved the distal segment of q12 and the proximal segment of q13.1 (15 cM). The severely affected female infant born at 38 weeks has clinical findings that may be related to haploinsufficiency of specific genes within 19q12.1βq13.1 that control important processes of normal development and cell function.

Duplication of a portion of Xq has been observed in males with abnormalities. In some cases, their mothers or even grandmothers had the same duplication but did not show any phenotypic abnormalities. However, a few cases of females with a de novo Xq duplication do present some abnormalities. We desc
We studied a familial dup(5q) present in a phenotypically normal father and his monozygotic twin daughters with different abnormal phenotypes. High-resolution chromosome analysis suggested that the duplicated segment was of region q15-21, which seems to be the smallest dup(5q) reported thus far. Thi
We report on the second case of duplication (4)(q12q13) with microcephaly, mental retardation, and minor facial anomalies. Duplications involving the distal region of chromosome 4q are well described and share common clinical findings. However, phenotypic abnormalities of duplications of the proxima
We report on a 5-year-old girl with multiple congenital anomalies, developmental delay, and a de novo unbalanced translocation between chromosomes X and 1[46,X,der(X)-t(X;1)(q24;q31.1)] resulting in partial trisomy 1q and partial monosomy Xq. The karyotype shows inactivation of the abnormal X chromo
We report on a patient with azoospermia, mild mental retardation, and minor physical anomalies. Chromosome analysis demonstrated the presence of additional material on the long arm of one chromosome 13. Forward chromosome painting using chromosome-specific libraries showed an insertion of material f
