overgrowth. Syndactyly is a variable manifestation. The disorder is rare and the majority
of affected individuals have been reported in the Afrikaner population of South Africa
(summary by Brunkow et al., 2001). - Genetic Heterogeneity of Sclerosteosis Sclerosteosis-2
(SOST2; 614305) is caused by mutation in the LRP4 gene (604270) on chromosome 11p11.2.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutations in the sclerostin gene (SOST, 605740.0001);
