Collection Method: clinical testing

The c.199A>G (p.I67V) alteration is located in exon 2 (coding exon 2) of the ZSWIM4 gene. This alteration results from a A to G substitution at nucleotide position 199, causing the isoleucine (I) at amino acid position 67 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
