A de novo Proximal 6q Deletion Confirmed by Array Comparative Genomic Hybridization / 대한진단검사의학회지

ABSTRACT

Deletions of chromosome 6q, particularly in the proximal region, are relatively rare. Here, we report on a de novo interstitial deletion of (6)(q13q16.2) in a girl with facial dysmorphism, congenital hip dislocation, porencephaly, and brain atrophy. Array comparative genomic hybridization analysis showed arr 6q13q16.2(73,378,824-99,824,130), demonstrating higher resolution than the conventional cytogenetic findings, del(6)(q12q15). The clinical data were analyzed and compared with those of similar patients previously reported in the literature.
