severe combined immunodeficiency, Athabaskan type (SCIDA)

Defects in DCLRE1C are the cause of severe combined immunodeficiency Athabaskan type (SCIDA). SCIDA is a variety of RS-SCID caused by a founder mutation in Athabascan-speaking native Americans, being inherited as an autosomal recessive trait with an estimated gene frequency of 2.1% in the Navajo population. Affected individuals exhibit clinical symptoms and defects in DNA repair comparable to those seen in RS-SCID.
