Summaries for Man1b1-Cdg

NIH Rare Diseases : 52 The following summary is from Orphanet , a European reference portal for information on rare diseases and orphan drugs. Orpha Number: 397941 Definition MAN1B1-CDG is a form of congenital disorders of N-linked glycosylation characterized by intellectual disability , delayed motor development, hypotonia and truncal obesity. Additional features include slight facial dysmorphism (hypertelorism, downslanting palpebral fissures, large, low-set ears, hypoplastic nasolabial fold, thin upper lip), hypermobility of the joints and skin laxity. The disease is caused by mutations in the gene MAN1B1 (9q34.3). Visit the Orphanet disease page for more resources.

MalaCards based summary : Man1b1-Cdg, also known as carbohydrate deficient glycoprotein syndrome type ii due to man1b1 deficiency, is related to congenital disorders of n-linked glycosylation and multiple pathway. An important gene associated with Man1b1-Cdg is MAN1B1 (Mannosidase Alpha Class 1B Member 1). Affiliated tissues include skin and brain, and related phenotypes are global developmental delay and infantile muscular hypotonia
