Genes affected

HELZ (HGNC:16878): (helicase with zinc finger) HELZ is a member of the superfamily I class of RNA helicases. RNA helicases alter the conformation of RNA by unwinding double-stranded regions, thereby altering the biologic activity of the RNA molecule and regulating access to other proteins (Wagner et al., 1999 [PubMed 10471385]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Oct 18, 2021

The c.4955G>A (p.R1652H) alteration is located in exon 31 (coding exon 28) of the HELZ gene. This alteration results from a G to A substitution at nucleotide position 4955, causing the arginine (R) at amino acid position 1652 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
