The c.905T>C (p.M302T) alteration is located in exon 9 (coding exon 8) of the BZW2 gene. This alteration results from a T to C substitution at nucleotide position 905, causing the methionine (M) at amino acid position 302 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
