Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2023The c.4171G>A (p.D1391N) 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 4171, causing the aspartic acid (D) at amino acid position 1391 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
