The c.629T>C (p.M210T) alteration is located in exon 8 (coding exon 8) of the SYCP2L gene. This alteration results from a T to C substitution at nucleotide position 629, causing the methionine (M) at amino acid position 210 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
