Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.1912G>A (p.A638T) alteration is located in exon 11 (coding exon 10) of the AKNAD1 gene. This alteration results from a G to A substitution at nucleotide position 1912, causing the alanine (A) at amino acid position 638 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
