About CCND1
The CCND1 gene (Cyclin D1) on chromosome 11q13 The t(11;14)(q13;q32) translocation fuse CCND1 to the immunoglobulin heavy chain locus, driving mantle cell lymphoma and multiple myeloma. Key targets include Exons 1–5 for comprehensive mutation screening.
Mutations: CCND1-IGH translocation, splicing variant | GC content: 55% | Target exons: Exons 1–5
CCND1 Primer Design Challenges
- Translocation breakpoints: t(11;14) breakpoints cluster in the 11q13 major translocation cluster (MTC) spanning ~1 kb requiring specific primers
- Alternative splicing: CCND1 variant transcripts (b, c, d) with alternative 3' exons require isoform-specific detection strategies
- Polymorphic A870G: rs603965 in exon 4 splice site affects mRNA splicing and may require redesign of flanking primers

Key SNPs to Avoid in Primer Binding Sites
When designing CCND1 primers, avoid these clinically significant variants:
- rs603965 (A870G) — Exon 4 splice site variant affecting cyclin D1b expression
- rs9344 (G870A) — Synonymous polymorphism in exon 4
Clinical Validation Required
All CCND1 primers designed with VigyanLLM are for research use only. Clinical diagnostic applications require additional wet-lab validation, Sanger sequencing confirmation, and regulatory approval before patient use.
