Arthrogryposis-hyperkeratosis syndrome, lethal form
MONDO:0008826Arthrogryposis-hyperkeratosis syndrome, lethal form is an arthrogryposis syndrome, described in two siblings to date, characterized by the association of multiple congenital joint contractures (of the large joints, fingers and toes) and hyperkeratosis (i.e. thick, scaling and fissured skin), with death occurring in early infancy. There have been no further reports in the literature since 1993.
Also known as: Johnston-Aarons-Schelley syndrome, Johnston Aarons Schelley syndrome, Joint contractures, hyperkeratosis, and severe hypoplasia of the posterior columns, arthrogryposis with hyperkeratosis

Gene sequencing uncovers mysterious fetal malformations
Knowledge-focused CompletedThis study tested whether a powerful DNA test called high-throughput exome sequencing can find genetic causes of multiple birth defects in fetuses when standard exams fail. Researchers studied 100 fetuses with at least two malformations and no prior diagnosis. They compared the n…
