Collection Method: clinical testing

The c.46G>C (p.V16L) alteration is located in exon 1 (coding exon 1) of the BZW1 gene. This alteration results from a G to C substitution at nucleotide position 46, causing the valine (V) at amino acid position 16 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
