Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.3950C>T (p.S1317L) alteration is located in exon 21 (coding exon 20) of the AKNA gene. This alteration results from a C to T substitution at nucleotide position 3950, causing the serine (S) at amino acid position 1317 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
