Description

Goal

Investigate the biological significance of snRNP/spliceosomal gene enrichment in subtelomeric PHRs.

Context

Our PHR-only GO enrichment found that 8 out of 22 query genes are involved in spliceosomal snRNP assembly. The top hits are:

Formation of quadruple SL/U4/U5/U6 snRNP (p=9.9e-4)
Spliceosomal tri-snRNP complex assembly (p=1.1e-3)
U4 snRNA binding (MF, p=9.1e-5) — strongest single hit
mRNA splicing via spliceosome
Protein-RNA complex assembly/organization

This signal persists (and improves) when excluding acrocentric PHRs — it's genome-wide.

Questions to answer

Which 8 genes are these? Read from phrs.no_acro.gene_names.txt and cross-reference with the g:Profiler results or the GFF3 to identify the specific genes annotated to snRNP/spliceosome GO terms. Check the CSV files for gene lists within each term.
What do these genes do? For each of the 8, briefly describe: gene name, full name, function, known disease associations, whether it's protein-coding or pseudogene.
Why would spliceosomal genes cluster in subtelomeric PHRs? Are these known to be in multi-copy gene families? Are they pseudogenes of spliceosomal components? (snRNA genes like U4, U5, U6 are known to exist in tandem arrays — are the 8 genes related to snRNA pseudogenes?)
Is there precedent in the literature for spliceosomal component genes being enriched in subtelomeric regions?
Connection to T2T/CHM13: Were any of these genes newly resolved by the T2T assembly? Check Angela's 'Novel T2T' sheet concept from the xlsx if accessible.

Output

Log a structured summary with gene identities, functions, and a 2-paragraph interpretation of why this signal exists and what it means for the PHR paper.

Validation

All 8 genes are identified by name
Each gene has a brief functional annotation
The biological interpretation addresses whether these are functional genes vs pseudogenes
Literature context is provided

2026-03-31T22:30:00.067964746+00:00 Identified 8 LOC genes driving snRNP enrichment signal: LOC101928344, LOC101928626, LOC101928932, LOC101929650, LOC101929756, LOC101929819, LOC101929823, LOC101929828
2026-03-31T22:30:12.734364377+00:00 All 8 genes are lncRNAs (long non-coding RNAs), not protein-coding. Located across multiple chromosomes, some with multi-copy. This suggests they may be pseudogenes or regulatory RNAs related to snRNP components.
