Summaries for Galloway-Mowat Syndrome 2, X-Linked

UniProtKB/Swiss-Prot : 75 Galloway-Mowat syndrome 2, X-linked: A form of Galloway-Mowat syndrome, a severe renal-neurological disease characterized by early-onset nephrotic syndrome associated with microcephaly, central nervous system abnormalities, developmental delays, and a propensity for seizures. Brain anomalies include gyration defects ranging from lissencephaly to pachygyria and polymicrogyria, and cerebellar hypoplasia. Most patients show facial dysmorphism characterized by a small, narrow forehead, large/floppy ears, deep-set eyes, hypertelorism and micrognathia. Additional variable features are visual impairment and arachnodactyly. Most patients die in early childhood.

MalaCards based summary : Galloway-Mowat Syndrome 2, X-Linked, is also known as gamos2. An important gene associated with Galloway-Mowat Syndrome 2, X-Linked is LAGE3 (L Antigen Family Member 3). Affiliated tissues include brain, eye and kidney, and related phenotypes are nystagmus and intellectual disability

OMIM : 57 Galloway-Mowat syndrome is a renal-neurologic disease characterized by early-onset nephrotic syndrome associated with microcephaly, gyral abnormalities of the brain, and delayed psychomotor development. Most patients have dysmorphic facial features, often including hypertelorism, ear abnormalities, and micrognathia. Other features, such as arachnodactyly and visual impairment, are more variable. Most patients die in the first years of life (summary by Braun et al., 2017). For a general phenotypic description and a discussion of genetic heterogeneity of GAMOS, see GAMOS1 (251300). (301006)
