The c.361G>A (p.A121T) alteration is located in exon 2 (coding exon 2) of the SPATA3 gene. This alteration results from a G to A substitution at nucleotide position 361, causing the alanine (A) at amino acid position 121 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
