Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.4225G>A (p.A1409T) alteration is located in exon 22 (coding exon 21) of the AKNA gene. This alteration results from a G to A substitution at nucleotide position 4225, causing the alanine (A) at amino acid position 1409 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
