Patients with TSC2 mutations were more likely to have a cyst-like tuber than patients with TSC1 mutation (p = 0.002) or patients with no mutation identified (p = 0.039). While the OMIM database is open to the public, users seeking information about a personal (1971) reported death due to rupture of an aortic aneurysm in a 3-year-old boy, and Larbre et al. Both parents of 84 of the ascertained cases were assessed for signs of tuberous sclerosis; in 51 pairs of parents no evidence of the condition was seen, indicating that up to 60% of the cases were new mutations. Overlapping neurologic and cognitive phenotypes in patients with TSC1 or TSC2 mutations. Approximately 10 to 30% of cases of tuberous sclerosis are due to mutations in the TSC1 gene: the frequency of cases due to mutations in the TSC2 gene is consistently higher. 29: 861-866, 1992.

Despite some of these small differences, Jansen et al. (1999) identified 6 families with mosaicism in a series of 62 unrelated families with a mutation in either the TSC1 or the TSC2 gene.
