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]

The c.237C>G (p.D79E) alteration is located in exon 2 (coding exon 2) of the OTP gene. This alteration results from a C to G substitution at nucleotide position 237, causing the aspartic acid (D) at amino acid position 79 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
