The c.860A>T (p.D287V) alteration is located in exon 9 (coding exon 8) of the BZW2 gene. This alteration results from a A to T substitution at nucleotide position 860, causing the aspartic acid (D) at amino acid position 287 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
