Maternal uniparental disomy of chromosome 21 [upd(21)mat] was found previously in a normal female and in 2 cases of early embryonic failure. We present a phenotypically normal child with upd(21)mat due to a de novo der(21;21)(q10;10). This finding suggests that chromosome 21 is not imprinted in the maternal germline. Am.

We describe a liveborn infant with uniparental disomy (UPD) with trisomy 15 mosaicism. Third trimester amniocentesis yielded a 46W47,XX, + 15 karyotype. Symmetrical growth retardation, distinct craniofacies, congenital heart disease, severe hypotonia and minor skeletal anomalies were noted. The infa
Uniparental disomy (UPD) is the abnormal inheritance of two copies of a chromosome from the same parent. Possible mechanisms for UPD include trisomy rescue, monosomy rescue, gametic complementation, and somatic recombination. Most of these mechanisms can involve rearranged chromosomes, particularly
Stable centromeric breakage in nonacrocentric chromosomes and balanced reciprocal translocation mosaicism are both rare events. We studied a family in which the mother had mosaicism for a balanced reciprocal translocation between chromosomes 10 and 16 which was associated with a break in chromosome
We describe a unique patient with complete androgen insensitivity syndrome and a 47,XXY karyotype. Androgen receptor assay using cultured pubic skin fibroblasts showed no androgen-binding capacity. Sequence analysis of the androgen receptor gene demonstrated two nonsense mutations, one in exon D and
