Summaries for Immunodeficiency 64

OMIM : 56 Immunodeficiency-64 (IMD64) is an autosomal recessive primary immunodeficiency characterized by onset of recurrent bacterial, viral, and fungal infections in early childhood. Laboratory studies show variably decreased numbers of T cells, with lesser deficiencies of B and NK cells. There is impaired T-cell proliferation and activation; functional defects in B cells and NK cells may also be observed. Patients have increased susceptibility to EBV infection and may develop lymphoproliferation or EBV-associated lymphoma. Some patients may develop features of autoimmunity (summary by Salzer et al., 2016, Mao et al., 2018, and Winter et al., 2018). (618534)

MalaCards based summary : Immunodeficiency 64, is also known as imd64. An important gene associated with Immunodeficiency 64 is RASGRP1 (RAS Guanyl Releasing Protein 1). Affiliated tissues include t cells, nk cells and b cells, and related phenotypes are splenomegaly and failure to thrive

UniProtKB/Swiss-Prot : 73 Immunodeficiency 64: An autosomal recessive primary immunodeficiency characterized by recurrent bacterial, viral and fungal infections, variably decreased numbers of T cells, deficiencies of B and NK cells, and increased susceptibility to Epstein-Barr virus (EBV) infection. Patients may develop lymphoproliferation or EBV-associated lymphoma. Some patients may develop features of autoimmunity.
