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]

The c.4754A>G (p.H1585R) alteration is located in exon 31 (coding exon 28) of the HELZ gene. This alteration results from a A to G substitution at nucleotide position 4754, causing the histidine (H) at amino acid position 1585 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
