RT Journal Article SR Electronic T1 Recessive form of Freeman-Sheldon's syndrome or 'whistling face',. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 139 OP 141 DO 10.1136/jmg.14.2.139 VO 14 IS 2 A1 A F Alves A1 E S Azevedo YR 1977 UL http://jmg.bmj.com/content/14/2/139.abstract AB Freeman-Sheldon's syndrome is a rare genetic disease inherited as an autosomal dominant trait in some families but showing sporadic appearance in the majority of the reported cases. In the present paper we report a family having two affected children from normal consanguineous parents suggesting that Freeman-Sheldon's syndrome may be heterogeneous from the genetic point of view.
