关于 DNA2

Cytogenetic location: 10q21.3 Genomic coordinates (GRCh38): 10:68,414,064-68,472,521 (from NCBI)

This gene has 8 transcripts (splice variants), 172 orthologues, 10 paralogues and is associated with 4 phenotypes. Broad expression in lymph node (RPKM 2.7), testis (RPKM 1.9) and 24 other tissues.

功能概要

该基因编码 DNA2/NAM7 解旋酶家族的一个成员。编码的蛋白质是一种保守的解旋酶/核酸酶,参与维持线粒体和核 DNA 的稳定性。该基因的突变与常染色体显性遗传性进行性外眼肌麻痹 6 (PEOA6) 和 Seckel 综合征 8 相关。已发现该基因的选择性剪接转录物变体。[RefSeq 提供,2014 年 9 月]

This gene encodes a member of the DNA2/NAM7 helicase family. The encoded protein is a conserved helicase/nuclease involved in the maintenance of mitochondrial and nuclear DNA stability. Mutations in this gene are associated with autosomal dominant progressive external ophthalmoplegia-6 (PEOA6) and Seckel syndrome 8. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2014]
