Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2022The c.2266A>G (p.K756E) alteration is located in exon 19 (coding exon 19) of the OVCH1 gene. This alteration results from a A to G substitution at nucleotide position 2266, causing the lysine (K) at amino acid position 756 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
