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 GeneticsAug 11, 2022The c.293A>T (p.Q98L) alteration is located in exon 2 (coding exon 2) of the OTP gene. This alteration results from a A to T substitution at nucleotide position 293, causing the glutamine (Q) at amino acid position 98 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
