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);

Neoplasia : Basal cell carcinoma; Squamous cell carcinoma; Osteogenic sarcoma;

Prefixed ID : #268400;
