Comment on publications: added publication from OMIM : a single report van Zelm et al. (2010) PMID:20237408 (2010) In a Moroccan girl, born of consanguineous parents, with common variable immunodeficiency-6, van Zelm et al. (2010) identified a homozygous G-to-A transition in intron 6 of the CD81 gene, resulting in use of a cryptic splice site, generation of a frameshift, and premature termination. The CD81-deficient case showed autoimmune and inflammatory complications. Initially, this CD81 mutation was assumed to completely abolish CD81 protein expression, and thought in the absence of expression, CD19 expression was halved as it was thought that it provides docking sites for various signal transduction pathway molecules PMID: 14530327, 20237408. However, it was recently demonstrated by Vences-Catalán et al. (2015) PMID:25739915 that in fact a truncated CD81 protein was produced, both the mutant CD81 and the normal CD19 protein were retained intracellularly, resulting in absent CD81 and CD19 surface expression.

Comment on phenotypes: added MIMid from OMIM. Common variable immunodeficiency (CVID) is the largest group of symptomatic primary immune deficiencies; it is characterized by hypogammaglobulinemia, poor response to vaccines and increased susceptibility to infections.

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.
