Two novel mutations in a purine nucleoside phosphorylase (PNP)-deficient patient.

Abstract excerpt

Purine nucleoside phosphorylase (PNP) deficiency is a rare autosomal recessive disease, which presents clinically as severe combined immunodeficiency (SCID). We report here two novel mutations in the PNP gene that result in SCID phenotype, in a single patient. The maternal-derived allele carries a C to T transition in exon 2 resulting in a premature stop codon at amino acid 57. The paternal-derived mutation is a...
