Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.922A>G (p.I308V) alteration is located in exon 8 (coding exon 8) of the ANKMY2 gene. This alteration results from a A to G substitution at nucleotide position 922, causing the isoleucine (I) at amino acid position 308 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
