The c.410T>C (p.L137P) alteration is located in exon 6 (coding exon 5) of the BZW2 gene. This alteration results from a T to C substitution at nucleotide position 410, causing the leucine (L) at amino acid position 137 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
