Description

DNA sequence analysis of the RECQL4 gene demonstrated a sequence change, c.1130A>G, in exon 5 that results in an amino acid change, p.Gln377Arg. This sequence change has been described in gnomAD with a low frequency of 0.0056% (dbSNP rs944826681) in the East Asian sub-population. The p.Gln377Arg change affects a highly conserved amino acid residue located in a domain of the RECQL4 protein that is not known to be functional. The p.Gln377Arg substitution appears to be deleterious using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD). This sequence change does not appear to have been previously described in patients with RECQL4-related disorders. Due to the lack of sufficient evidences, the clinical significance of the p.Gln377Arg change remains unknown at this time.
