Summaries for Multiple Pterygium Syndrome, Lethal Type

NIH Rare Diseases : 53 Multiple pterygium syndrome lethal type is a very rare genetic condition affecting the skin, muscles and skeleton. It is characterized by minor facial abnormalities, prenatal growth deficiency, spine defects, joint contractures, and webbing (pterygia) of the neck, elbows, back of the knees, armpits, and fingers.  Fetuses with this condition are usually not born. Some of the prenatal complications include cystic hygroma, hydrops, diaphragmatic hernia, polyhydramnios, underdevelopment of the heart and lungs, microcephaly, bone fusions, joint dislocations, spinal fusion, and bone fractures. Both X-linked and autosomal recessive inheritance have been proposed.Mutations in the CHRNG, CHRNA1, and CHRND genes have been found to cause this condition.

MalaCards based summary : Multiple Pterygium Syndrome, Lethal Type, also known as lethal multiple pterygium syndrome, is related to multiple pterygium syndrome, escobar variant and multiple pterygium syndrome, x-linked, and has symptoms including edema An important gene associated with Multiple Pterygium Syndrome, Lethal Type is CHRND (Cholinergic Receptor Nicotinic Delta Subunit), and among its related pathways/superpathways are CREB Pathway and Transmission across Chemical Synapses. Affiliated tissues include bone, lung and heart, and related phenotypes are cleft palate and epicanthus

UniProtKB/Swiss-Prot : 75 Multiple pterygium syndrome, lethal type: Multiple pterygia are found infrequently in children with arthrogryposis and in fetuses with fetal akinesia syndrome. In lethal multiple pterygium syndrome there is intrauterine growth retardation, multiple pterygia, and flexion contractures causing severe arthrogryposis and fetal akinesia. Subcutaneous edema can be severe, causing fetal hydrops with cystic hygroma and lung hypoplasia. Oligohydramnios and facial anomalies are frequent.
