The c.1042C>T (p.R348C) alteration is located in exon 7 (coding exon 7) of the FAM117A gene. This alteration results from a C to T substitution at nucleotide position 1042, causing the arginine (R) at amino acid position 348 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
