Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 08, 2021The c.3823G>A (p.G1275S) alteration is located in exon 20 (coding exon 19) of the AKNA gene. This alteration results from a G to A substitution at nucleotide position 3823, causing the glycine (G) at amino acid position 1275 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
