✦ Synopsis

We report on a patient with dup(l7p) and monosomy (1Oq) resulting from a familial translocation. Manifestations typical of both syndromes were present. The overall development of this patient was better by comparison with similar reported cases of either anomaly. Our evaluation detected severe gross motor delay and signs of a demyelinating peripheral neuropathy. This patient is trisomic for the region of 17p which includes the peripheral myelin protein-22 (PMP-22) gene, known to be duplicated in Charcot-Marie-Tooth neuropathy type 1A (CMTlA). Our analysis in this patient suggests that trisomy for the PMP-22 gene led to the demyelinating neuropathy and contributed to his severe motor developmental delay.

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
