The c.3778T>C (p.C1260R) alteration is located in exon 19 (coding exon 19) of the FAM208A gene. This alteration results from a T to C substitution at nucleotide position 3778, causing the cysteine (C) at amino acid position 1260 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
