The c.482G>C (p.C161S) alteration is located in exon 5 (coding exon 5) of the SPATA9 gene. This alteration results from a G to C substitution at nucleotide position 482, causing the cysteine (C) at amino acid position 161 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
