Comment on list classification: Changed from Amber to Green, there more than three unrelated families with biallelic loss-of-function mutationsCreated: 18 Jun 2018, 12:43 p.m.
Comment on publications: added publications to further support DOCK2 variants resulting in PID phenotypeCreated: 18 Jun 2018, 12:42 p.m.
From PMID: 28694805 (2017). The inbred population of the MENA region provides a great opportunity to identify monogenic PIDs through novel next-generation sequencing technology. Middle East and North Africa region (MENA) populations are of different ethnic origins. Studies of PIDs in the region had contributed into the discovery and the understanding of large numbers of these disorders. For example, more than 12 novel PID genes were discovered through studying patients from the MENA region in the last 2 years, one of which include DOCK2 (PMID:26083206)Created: 18 Jun 2018, 12:42 p.m.
Clinically, DOCK8 deficiency is characterized by allergic inflammation as well as susceptibility towards infections, autoimmunity and malignancy.Created: 18 Jun 2018, 12:29 p.m.
Comment on publications: Added Dobbs (2015) PMID:26083206 reported 5 unrelated children with immunodeficiency-40 (IMD40; 616433) and identified 7 different biallelic mutations in the DOCK2 gene. The mutations were found by whole-exome sequencing, sometimes combined with linkage analysis, and segregated with the disorder in the families. Four of the mutations led to premature termination of the protein, and 3 were missense mutations affecting conserved residues, consistent with a loss of function.Created: 18 Jun 2018, 12:27 p.m.
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.Created: 20 Apr 2018, 12:25 p.m.
