A rare 3q13.31 microdeletion including GAP43 and LSAMP genes.

ABSTRACT:

Background

Interstitial deletions affecting the proximal long arm of chromosome 3 have been rarely reported in the literature. The deleted segments vary in localization and size with different breakpoints making genotype-phenotype correlation very difficult. Until now, a girl with a 1.9-Mb interstitial deletion of 3q13.2q13.31 and 14 novel patients with deletions in 3q11q23 have been reported.

Results

Here we report on a 7-year-old girl with neuropsychiatric disorders and renal, vascular and skeletal anomalies. Array-CGH analysis revealed a small rare inherited 3q13.31 deletion containing only two genes, GAP43 and LSAMP. The mutation analysis of the two genes was negative on the other non-deleted chromosome. GAP43 is considered a crucial component for an effective regenerati
