摘要:
人类基因组的单核苷酸变异(single nucleotide variants,SNVs)位点数量庞大,寻找其中真正的致病位点仍然是遗传学研究中的一项重要挑战。最近, N6-甲基胞嘧啶(m6A)修饰在许多基本生物过程和各种疾病中的关键作用被揭示,已经成为一个研究热点。因此,评估变异对m6A修饰的影响至关重要。m6Avar数据库由中山大学超级计算机学院的任间教授团队开发,是可能影响m6A修饰的m6A相关变异综合数据库,它将通过m6A修饰的功能来解释变异的功能。m6A相关变异来源于3种不同的m6A资源,包括miCLIP/PA-m6A-seq实验(高可信度),MeRIP-Seq实验(中可信度)和全转录组预测(低可信度)。数据库同时也整合了与变异相关的RBP结合区,miRNA-靶点和剪接位点以帮助用户研究m6A相关变异对转录后调控的影响,为进一步的功能研究提供了很多可以挖掘的资源。同时,该数据库还整合了来自全基因组关联研究( genome-wide association studies (GWAS)和ClinVar的数据,所以m6AVar也是研究m6A相关变异和疾病间的关系的一种有用资源。

数据总览:
m6AVar数据库收集了来源于dbSNP和TCGA的百万个位点信息, 成千上万的有实验证据的m6A修饰位点信息(来源于7个m6A 单核苷酸分辨率交联与免疫沉淀(miCLIP)实验数据,2个 PA-m6A-Seq实验数据和244个MeRIP-Seq实验数据),以及大量的预测m6A位点数据。目前,m6Avar数据库注释了414,241个 m6A相关变异位点,包括dbSNP 来源的352,014 m6A-associated germline mutations和TCGA来源的 62,227 m6A-associated somatic mutations.
