A type of severe combined immunodeficiency disease characterised by severe and recurrent infections, diarrhoea, failure to thrive, and cell sensitivity to ionising radiation. Prevalence is unknown. Results from null mutations in the DCLRE1C gene (10p13) that lead to a defect in the V(D)J recombination and thus to an early arrest of both B and T cell maturation. Transmission is autosomal recessive. [from
