The c.1314C>G (p.S438R) alteration is located in exon 10 (coding exon 10) of the SERINC3 gene. This alteration results from a C to G substitution at nucleotide position 1314, causing the serine (S) at amino acid position 438 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
