Collection Method: clinical testing

The c.799G>A (p.V267M) alteration is located in exon 8 (coding exon 7) of the YIPF2 gene. This alteration results from a G to A substitution at nucleotide position 799, causing the valine (V) at amino acid position 267 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
