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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 16, 2024The c.698C>G (p.A233G) alteration is located in exon 3 (coding exon 3) of the OTP gene. This alteration results from a C to G substitution at nucleotide position 698, causing the alanine (A) at amino acid position 233 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
