RNVU1-15: RNVU1-15 is a promoter for Pol II snRNA transcription, with a high median precision score of 0.86 [PMC9758055]. It is moderately to highly expressed in the nervous system and whole blood [PMC7220435]. RNVU1-15 is one of the nine snRNAs in the snRNA signature, which also includes RNU1-16P, RNU6-1031P, RNU6-258P, RNU6-335P, RNU6-485P, RNU6-549P, RNU6-98P, and RNU6ATAC26P [PMC6855622]. Some of these ncRNAs, including POLR2KP2 and TUBB2BP1 in addition to RNVU1-15 and others mentioned above, are moderately to highly expressed in neurons and may be associated with ASD pathogenesis in the brain [PMC7828397]. Furthermore, a study identified RNVU1-15 as one of the potential biomarkers for colorectal adenocarcinoma (COAD) for the first time [PMC9444393]. This study also investigated the molecular mechanism affecting initial lymphatic metastasis in COAD patients and identified six core genes including RNVU1-15 [PMC9444393]. Univariate analysis showed that both RNVU1-15 and another gene called RNA4-U2 (RNU4-U2) were significant and could be included in a multivariate regression model [PMC9444393]. Additionally, both RNA4-U2 (RNU4-U2) and RNVU1-15 are involved in RNA processing related to suicide and autism [PMC9444393].
