Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 24, 2023The c.4279C>A (p.L1427M) alteration is located in exon 22 (coding exon 21) of the AKNA gene. This alteration results from a C to A substitution at nucleotide position 4279, causing the leucine (L) at amino acid position 1427 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
