Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.3752A>T (p.D1251V) alteration is located in exon 19 (coding exon 18) of the AKNA gene. This alteration results from a A to T substitution at nucleotide position 3752, causing the aspartic acid (D) at amino acid position 1251 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
