Genes affected

SLF2 (HGNC:17814): (SMC5-SMC6 complex localization factor 2) Enables ubiquitin protein ligase binding activity. Involved in several processes, including positive regulation of cellular component organization; positive regulation of double-strand break repair; and protein localization to site of double-strand break. Located in chromatin; nucleoplasm; and site of double-strand break. [provided by Alliance of Genome Resources, Apr 2022]
