Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.43G>A (p.V15M) alteration is located in exon 1 (coding exon 1) of the HYPK gene. This alteration results from a G to A substitution at nucleotide position 43, causing the valine (V) at amino acid position 15 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
