Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 22, 2023The c.1397A>G (p.K466R) alteration is located in exon 13 (coding exon 13) of the OVCH2 gene. This alteration results from a A to G substitution at nucleotide position 1397, causing the lysine (K) at amino acid position 466 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
