Table 2

Simulations created with Gensim and analysed with Genehunter. Successive simulations were performed with increasing proportion of affected sibling pairs generated randomly (that is, not linked to presumed locus)

  • λs , relative risk in sibling versus general population risk.

  • % Linked, per cent of affected sibling pairs linked to presumed locus.

  • Avg MLS, average multipoint LOD score seen in 100 (a), 200 (b), or 500 (c) affected sibling pairs after 1000 replicates.

  • No sims MLS >3.6, number/1000 simulations where the multipoint LOD score reached a threshold of 3.6.

  • % Loss, per cent fewer simulations that reached a threshold of 3.6.

  • NA, not applicable.
