MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein belonging to the leucine-rich repeat family of proteins, which are involved in diverse biological processes, including cell adhesion, cellular trafficking, and hormone-receptor interactions. This family member is a putative four-pass transmembrane protein that plays a role in B cell development. Defects in this gene cause autosomal dominant non-Bruton type agammaglobulinemia, an immunodeficiency disease resulting from defects in B cell maturation. Multiple alternatively spliced transcript variants, which encode the same protein, have been identified for this gene. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous for a knock-out allele exhibit prenatal lethality and premature death, growth retardation, sterility, multiple tissue abnormalities, a severe block in early thymic development, and impaired peripheral T cell function. B cell development is modestly impaired but B cell function is normal. [provided by MGI curators]
