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.5767T>C (p.F1923L) alteration is located in exon 33 (coding exon 30) of the HELZ gene. This alteration results from a T to C substitution at nucleotide position 5767, causing the phenylalanine (F) at amino acid position 1923 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
