Interstitial deletions of chromosome 6q are a relatively rare finding. Deletions have ranged from the loss of a single band to larger deletions spanning multiple bands. The clinical phenotype varies, but some features commonly seen include cardiac anomalies, hypotonia, facial dysmorphism and mental retardation. To further delineate the syndrome, we report an infant with facial dysmorphism, ectrodactyly and tetralogy of Fallot owing to interstitial deletion 6q16.1-6q22.32. On array comparative genomic hybridization analysis, the deletion spanned from the 93 377 323rd base to the 127 650 582nd base on chromosome 6 [coordinates are based on Human Mar. 2006 (hg18) assembly of International Human Genome Sequencing Consortium]. A literature review identified 16 additional cases with overlapping interstitial deletions of chromosome 6q between q13 and q23.1. Genotype-phenotype correlations are considered.
