RecQ like helicase

Also known as: RECON, RECQL1, RecQ1

RECQL encodes a DNA helicase that unwinds DNA and resolves DNA structural intermediates during replication and repair, playing a critical role in maintaining genome stability. Biallelic mutations cause RECON progeroid syndrome, an autosomal recessive disorder characterized by premature aging features. The gene shows very low constraint against loss-of-function variants (LOEUF 1.31), consistent with recessive inheritance where heterozygous carriers are typically unaffected.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
