Genes affected
OTOR (HGNC:8517): (otoraplin) This gene encodes a member of the melanoma-inhibiting activity gene family. The encoded protein is secreted via the Golgi apparatus and may function in cartilage development and maintenance. A frequent polymorphism in the translation start codon of this gene can abolish translation and may be associated with forms of deafness. [provided by RefSeq, Jul 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2023The c.175A>G (p.N59D) alteration is located in exon 2 (coding exon 2) of the OTOR gene. This alteration results from a A to G substitution at nucleotide position 175, causing the asparagine (N) at amino acid position 59 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
