Description
Homo sapiens hsa-let-7f-2 precursor miRNA

Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?

MIRLET7F2 is a microRNA gene located on the X chromosome, specifically within a 122 kb maternal duplication at Xp11.22, which has been suggested to have potential epigenetic effects [PMC9338470]. This gene is part of a custom gene panel designed for pediatric cancer mutation profiling, which includes various microRNA genes known to be involved in cancer biology [PMC7341754]. Notably, MIRLET7F2 is one of the abundant miRNAs secreted by lymphoid tumor cell lines, indicating its significance in the context of lymphoid tumors [PMC9210832]. Additionally, MIRLET7F2 is involved in potential auto-regulation mechanisms as it targets MIRLET7BHG along with other members of the let-7 family [PMC7961530]. The targeted capture for mutation profiling includes MIRLET7F2 among other critical genes and regions associated with cancer to facilitate comprehensive genomic analysis and understanding of its role in oncogenesis [PMC7815088].
