 Yunis–Varon syndrome also causes digital anomalies as most patients show aplasia (absence) of thumbs as well as distal phalanges or hypoplasia (underdevelopment) of proximal phalanx with absence and/or agenesis of halluces' (big toes') distal phalanxes sometimes with absent.Pelvic dysplasia may also be present, causing hips to be retracted and delineated through bilateral dislocation.These deformities in addition to microcephaly and reduced ossification from the disease might be partially due to the affected individual's under-mineralized skeleton.
