Description : The Al-Awadi/Raas-Rothschild/Schinzel phocomelia syndrome (AARRS) is a rare autosomal
recessive disorder characterized by severe malformations of upper and lower limbs
with severely hypoplastic pelvis and abnormal genitalia. The disorder is believed
to represent a defect of dorsoventral patterning and outgrowth of limbs (summary by
Kantaputra et al., 2010).;
Inheritance : Autosomal recessive;
