Description

The c.662C>T (p.A221V) alteration is located in exon 5 (coding exon 4) of the HELZ2 gene. This alteration results from a C to T substitution at nucleotide position 662, causing the alanine (A) at amino acid position 221 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
