Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.4210C>T (p.R1404W) alteration is located in exon 22 (coding exon 21) of the AKNA gene. This alteration results from a C to T substitution at nucleotide position 4210, causing the arginine (R) at amino acid position 1404 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
