Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2023The c.2284G>A (p.D762N) alteration is located in exon 15 (coding exon 14) of the AKNAD1 gene. This alteration results from a G to A substitution at nucleotide position 2284, causing the aspartic acid (D) at amino acid position 762 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
