Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 23, 2022The c.2370A>G (p.I790M) alteration is located in exon 15 (coding exon 14) of the AKNAD1 gene. This alteration results from a A to G substitution at nucleotide position 2370, causing the isoleucine (I) at amino acid position 790 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
