The c.1138C>T (p.R380W) alteration is located in exon 11 (coding exon 10) of the FAM114A2 gene. This alteration results from a C to T substitution at nucleotide position 1138, causing the arginine (R) at amino acid position 380 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
