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.857A>G (p.N286S) alteration is located in exon 3 (coding exon 3) of the OTP gene. This alteration results from a A to G substitution at nucleotide position 857, causing the asparagine (N) at amino acid position 286 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
