New case of interstitial deletion 12(q15-q21.2) in a girl with facial dysmorphism and mental retardation.
Interstitial deletions of the long arm of chromosome 12 are rare rearrangements with only 15 cases reported in the literature. The phenotype may include facial dysmorphism, developmental delay, ectodermal abnormalities, cardiac and renal malformations depending on breakpoints' position. Here, we describe a third case of 12(q15-q21.2) deletion ascertained through CGH-array analyses and provide a 5-year follow-up. The patient presented with pre- and postnatal growth retardation, congenital heart defect, developmental delay, and facial dysmorphism changing with age, underlining the importance of long-term follow-up. We compared this new case with previous observations of 12q deletions in order to propose phenotype-karyotype correlations.
