Olivia Niblock (Genomics England Curator)

Comment on list classification: Expert review green, however internal curation has listed this gene as low evidence. It appears that variants in this gene are linked to SHORT syndrome, Agammaglobulinaemia and Immunodeficiency, some of the symptoms of which can be chronic diarrhea seen only in some patients.
Unable to find strong evidence directly linking variants in this gene to gastrointestinal phenotypes.

Comment on mode of inheritance: Sourced from the A- or hypo-gammaglobulinaemia gene panel version 1.4.
Created: 12 Oct 2016, 4:18 p.m.
Comment on list classification: Promoted from red due to expert review. Confirmed DD gene for AGAMMAGLOBULINEMIA 7, AUTOSOMAL RECESSIVE and is green on the A- or hypo-gammaglobulinaemia gene panel with 5 green reviews.
