Summaries for Warburg Micro Syndrome 2

About this section
UniProtKB/Swiss-Prot : 76 Warburg micro syndrome 2: A rare syndrome characterized by microcephaly, microphthalmia, microcornia, congenital cataracts, optic atrophy, cortical dysplasia, in particular corpus callosum hypoplasia, severe mental retardation, spastic diplegia, and hypogonadism.

MalaCards based summary : Warburg Micro Syndrome 2, also known as micro syndrome 2, is related to steroid-induced glaucoma and rab18 deficiency. An important gene associated with Warburg Micro Syndrome 2 is RAB3GAP2 (RAB3 GTPase Activating Non-Catalytic Protein Subunit 2), and among its related pathways/superpathways are Vesicle-mediated transport and Golgi-to-ER retrograde transport. Affiliated tissues include brain and eye, and related phenotypes are macrotia and short nose

Disease Ontology : 12 A Warburg micro syndrome that has material basis in autosomal recessive inheritance of homozygous or compound heterozygous mutation in the RAB3GAP2 gene on chromosome 1q41.
