The c.2793T>G (p.C931W) alteration is located in exon 19 (coding exon 19) of the SEL1L3 gene. This alteration results from a T to G substitution at nucleotide position 2793, causing the cysteine (C) at amino acid position 931 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
