Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2022The c.160G>A (p.D54N) alteration is located in exon 2 (coding exon 2) of the OCM2 gene. This alteration results from a G to A substitution at nucleotide position 160, causing the aspartic acid (D) at amino acid position 54 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
