The c.1291G>A (p.V431I) alteration is located in exon 16 (coding exon 15) of the SYCP1 gene. This alteration results from a G to A substitution at nucleotide position 1291, causing the valine (V) at amino acid position 431 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
