not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2023The c.913C>T (p.R305C) alteration is located in exon 4 (coding exon 3) of the ELAC1 gene. This alteration results from a C to T substitution at nucleotide position 913, causing the arginine (R) at amino acid position 305 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
