A RECESSIVELY INHERITED NONLETHAL FORM OF POPLITEAL PTERYGIUM SYNDROME

Two siblings, a 10-year-old boy and a 6-month-old girl, born in a Pale stinian family, with manifestations of popliteal pterygium syndrome ar e presented. This rare form of syndrome is usually assumed to be autos omal dominant. Parental consanguinity and lack of phenotype manifestat ion in the ancestry of the present family favoured an interpretation o f determination by an autosomal recessive trait.
