Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2021The c.260G>A (p.G87E) alteration is located in exon 2 (coding exon 2) of the OTOP3 gene. This alteration results from a G to A substitution at nucleotide position 260, causing the glycine (G) at amino acid position 87 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
