The c.1081G>A (p.V361I) alteration is located in exon 9 (coding exon 9) of the SMC5 gene. This alteration results from a G to A substitution at nucleotide position 1081, causing the valine (V) at amino acid position 361 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
