Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.256A>G (p.M86V) alteration is located in exon 2 (coding exon 2) of the BEND5 gene. This alteration results from a A to G substitution at nucleotide position 256, causing the methionine (M) at amino acid position 86 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
