Summaries for Hennekam Lymphangiectasia-Lymphedema Syndrome 2

UniProtKB/Swiss-Prot : 71 Hennekam lymphangiectasia-lymphedema syndrome 2: A form of Hennekam lymphangiectasia-lymphedema syndrome, a generalized lymph-vessels dysplasia characterized by intestinal lymphangiectasia with severe lymphedema of the limbs, genitalia and face. In addition, affected individuals have unusual facies and severe mental retardation. HKLLS2 individuals have lymphangiectasia variably affecting the gut, pericardium, lungs, kidneys, and genitalia. Other features include camptodactyly and rare syndactyly.

MalaCards based summary : Hennekam Lymphangiectasia-Lymphedema Syndrome 2, is also known as hklls2, and has symptoms including hypertelorism, hearing impairment and depressed nasal bridge. An important gene associated with Hennekam Lymphangiectasia-Lymphedema Syndrome 2 is FAT4 (FAT Atypical Cadherin 4). Affiliated tissues include lung and kidney.

OMIM : 53 Hennekam lymphangiectasia-lymphedema syndrome is an autosomal recessive disorder characterized by generalized lymphatic dysplasia affecting various organs, including the intestinal tract, pericardium, and limbs. Additional features of the disorder include facial dysmorphism and cognitive impairment (summary by Alders et al., 2014). For a discussion of genetic heterogeneity of Hennekam lymphangiectasia-lymphedema syndrome, see HKLLS1 (235510). (616006)
