Juberg-Hayward syndrome
Juberg-Hayward syndrome is a rare genetic syndrome characterised by cleft lip/palate, microcephaly, ptosis, short stature, hypoplasia or aplasia of thumbs, dislocation of radial head and fusion of humerus and radius. The abnormalities in the arm lead to restriction of movement in the elbow.
Genetics[edit | edit source]
This syndrome is cased by mutations in the establishment of cohesion 1 homolog 2 (ESCO2) gene.[1] This gene is located on the short arm of chromosome 8 (8p21.1).
Mutations in this gene also cause Roberts/SC phocomelia syndrome.
Juberg-Hayward syndrome is inherited in both an autosomal recessive and autosomal dominant fashion.
