Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 29, 2022The c.2203G>A (p.V735M) alteration is located in exon 14 (coding exon 13) of the AKNAD1 gene. This alteration results from a G to A substitution at nucleotide position 2203, causing the valine (V) at amino acid position 735 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
