ATP-dependent DNA helicase Q4

The gene RECQL4 encodes a DNA helicase that unwinds double-stranded DNA into single-stranded DNAs and may modulate chromosome segregation. This gene is predominantly expressed in thymus and testis. Mutations in this gene are autosomal recessive and cause Rothmund-Thomson, RAPADILINO and Baller-Gerold syndromes.
