Alternative titles and symbols : Rothmund-thomson syndrome;
Description : Rothmund-Thomson syndrome is rare autosomal recessive disorder characterized by skin
atrophy, telangiectasia, hyper- and hypopigmentation, congenital skeletal abnormalities,
short stature, premature aging, and increased risk of malignant disease (Simon et
al., 2010). - Genetic Heterogeneity of Rothmund-Thomson Syndrome Wang et al. (2003)
analyzed the RECQL4 gene in 33 RTS patients and found an absence of RECQL4 mutations
in 10 patients. Analysis of a family with an affected sib pair excluded RECQL4 as
a recessive locus for RTS in the family, arguing strongly for genetic heterogeneity
in RTS. Simon et al. (2010) stated that only 40 to 66% of patients with RTS have been
found to have mutation in the RECQL4 gene, indicating genetic heterogeneity.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the Req-like DNA helicase type 4 gene (RECQL4, 603780.0001);
