The c.946G>A (p.V316I) alteration is located in exon 10 (coding exon 4) of the SGMS1 gene. This alteration results from a G to A substitution at nucleotide position 946, causing the valine (V) at amino acid position 316 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
