Description

In affected members of the family with Bjornstad syndrome (BJS; 262000) in which Lubianca Neto et al. (1998) demonstrated linkage to 2q, Hinson et al. (2007) identified homozygosity for a C-to-T transition in the BCS1L gene, resulting in an arg183-to-his (R183H) substitution. Eight individuals in 2 sibships related as first cousins once removed were affected; the parents in each case were consanguineous.
