adducted thumbs-arthrogryposis syndrome, Christian type
MONDO:0008724
A type of arthrogryposis characterized by congenital cleft palate, microcephaly, craniostenosis and arthrogryposis (limitation of extension of elbows, flexed adducted thumbs, camptodactyly and clubfeet). Additional features include facial dysmorphism ("myopathic" stiff face, antimongoloid slanting, external ophthalmoplegia, telecanthus, low-set large malrotated ears, open mouth, mierogenia and high arched palate). Velopharyngeal insufficiency with difficulties in swallowing, increased secretion of the nose and throat, prominent occiput, generalized muscular hypotonia with mild cyanosis and no spontaneous movements, seizures, torticollis, areflexia, intellectual disability, hypertrichosis of the lower extremities, and scleredema (in the first days of life) are also observed. The disease often leads to early death. Transmission is autosomal recessive. No new cases of adducted thumbs-arthrogryposis, Christian type have been described since 1983.

Adducted thumb syndrome
Adducted thumb syndrome recessive form is a rare disease affecting multiple systems causing malformations of the palate, thumbs, and upper limbs. The name Christian syndrome derives from Joe. C. Christian, the first person to describe the condition. Inheritance is believed to be autosomal recessive, caused by mutation in the CHST14 (carbohydrate sulfotransferase 14) gene.
