Genes affected

OTP (HGNC:8518): (orthopedia homeobox) This gene encodes a member of the homeodomain (HD) family. HD family proteins are helix-turn-helix transcription factors that play key roles in the specification of cell fates. This protein may function during brain development. [provided by RefSeq, Jul 2008]

Ambry Genetics

May 04, 2023

The c.287G>A (p.G96D) alteration is located in exon 2 (coding exon 2) of the OTP gene. This alteration results from a G to A substitution at nucleotide position 287, causing the glycine (G) at amino acid position 96 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
