Mutation analysis should be performed to rule out gammac deficiency in children with functional severe combined immune deficiency despite apparently normal immunologic tests

J Pediatr. 2005 Oct;147(4):555-7. doi: 10.1016/j.jpeds.2005.05.010.

Abstract

To study the correlation between genotype and phenotype in x-linked SCID, we have characterized the presentation of 2 unrelated patients. Both had infections suggestive of immunodeficiency, but their immune function and lymphoid tissues were normal. They were found to have an identical R222C mutation in the gammac gene.
