The c.535C>T (p.R179C) alteration is located in exon 3 (coding exon 2) of the ELAC1 gene. This alteration results from a C to T substitution at nucleotide position 535, causing the arginine (R) at amino acid position 179 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
