Combined Immunodeficiency
Gene: CD3G
10 affected individuals from 5 unrelated families; homozygous and compound heterozygous variants (splicing, missense and small deletion variants) identified resulting in premature stop codons and truncated protein; multiple mouse models.
All individuals displayed immune deficiency and autoimmunity of variable severity. Some individuals presented at birth with failure to thrive due to lethal SCID features, whilst other CD3G- deficient individuals only display immunological phenotype and no other features. The most common immunologic profile includes partial T lymphocytopenia and low CD3, with normal B cells, NK cells, and immunoglobulins.Created: 22 Jul 2021, 12:18 a.m. | Last Modified: 26 Jul 2021, 11:53 p.m.
