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.4766G>C (p.S1589T) alteration is located in exon 31 (coding exon 28) of the HELZ gene. This alteration results from a G to C substitution at nucleotide position 4766, causing the serine (S) at amino acid position 1589 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
