Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.889A>G (p.I297V) alteration is located in exon 1 (coding exon 1) of the BORCS6 gene. This alteration results from a A to G substitution at nucleotide position 889, causing the isoleucine (I) at amino acid position 297 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
