Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.574G>A (p.V192M) alteration is located in exon 6 (coding exon 6) of the HAGHL gene. This alteration results from a G to A substitution at nucleotide position 574, causing the valine (V) at amino acid position 192 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
