The c.977T>C (p.L326P) alteration is located in exon 8 (coding exon 8) of the ZSWIM2 gene. This alteration results from a T to C substitution at nucleotide position 977, causing the leucine (L) at amino acid position 326 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
