Genes affected

DLX2 (HGNC:2915): (distal-less homeobox 2) Many vertebrate homeo box-containing genes have been identified on the basis of their sequence similarity with Drosophila developmental genes. Members of the Dlx gene family contain a homeobox that is related to that of Distal-less (Dll), a gene expressed in the head and limbs of the developing fruit fly. The Distal-less (Dlx) family of genes comprises at least 6 different members, DLX1-DLX6. The DLX proteins are postulated to play a role in forebrain and craniofacial development. This gene is located in a tail-to-tail configuration with another member of the gene family on the long arm of chromosome 2. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 12, 2024

The c.787G>T (p.G263C) alteration is located in exon 3 (coding exon 3) of the DLX2 gene. This alteration results from a G to T substitution at nucleotide position 787, causing the glycine (G) at amino acid position 263 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
