Abstract

The severe combined immunodeficiency (SCID) mutation has been postulated to affect a V(D)J recombinase activity involved in coding joint formation. Analysis of 38 joints from 34 distinct sequences of normally rearranged T cell receptor (TCR) gamma and delta genes from adult, SCID thymocytes reveals coding joints with an increased number of P nucleotides. One-third of P sequences are greater than or equal to 4 nucleotides in length and P elements of up to 15 bases are observed. This suggests that the SCID defect deregulates P nucleotide addition. Consequently, essential V(D)J recombination intermediates may seldom be generated.

摘要

严重联合免疫缺陷(SCID)突变被推测会影响参与编码连接形成的V(D)J重组酶活性。对来自成年SCID胸腺细胞中正常重排的T细胞受体(TCR)γ和δ基因的34个不同序列的38个连接进行分析,发现编码连接中P核苷酸数量增加。三分之一的P序列长度大于或等于4个核苷酸,并且观察到长达15个碱基的P元件。这表明SCID缺陷会使P核苷酸添加失调。因此,可能很少产生必需的V(D)J重组中间体。
