Flat chromosome necklace | sterling silver
The banded chromosome is the working chromosome. The shape a cytogeneticist photographs, bands, and reads to detect the abnormality that drives a disease. Karyotyping is more than a hundred years old and still in daily clinical use, because the banding pattern is one of the cleanest first looks at a genome. Worn here as a 21 mm sterling silver pendant.
The Science Behind Chromosome Banding
The Philadelphia chromosome, the first chromosomal abnormality linked to a specific cancer, was identified in 1960 by Peter Nowell and David Hungerford at the University of Pennsylvania. It is a translocation between chromosomes 9 and 22, written t(9;22), which fuses the BCR gene on chromosome 22 to the ABL1 gene on chromosome 9. The resulting BCR-ABL fusion protein drives the uncontrolled cell division of chronic myeloid leukaemia. The discovery established that cancer can have a specific, identifiable chromosomal basis, and led directly to imatinib (Gleevec), a targeted therapy designed to inhibit BCR-ABL. Imatinib turned CML from a fatal diagnosis into a manageable condition. None of it would have been possible without chromosome banding.

FAQ
Round chromosome or flat: which one for which person?
The flat version is the karyotype shape, the chromosome as bands on a page. People who teach genetics or work with cytogenetic karyotyping reach for the flat form because that is the form they read at the microscope. The round form is the metaphase three-dimensional structure that cell biologists and chromatin researchers tend to picture when they think about chromosomes. Both are biologically accurate, both available in silver and in gold vermeil.
What did the Philadelphia chromosome change about cancer biology?
It established that cancer can have a specific, identifiable chromosomal cause. Before 1960, cancer was understood as a generic disorder of cell division. The Philadelphia chromosome showed that one specific translocation produced one specific malignancy. The follow-on therapy, imatinib, was the first targeted cancer drug designed against a specific molecular lesion rather than a general cytotoxic mechanism. The whole field of precision oncology can be traced back to that 1960 paper.
What size is the pendant and what is the return policy?
925 sterling silver, 21 mm pendant on a 45 cm sterling silver chain with a 5 cm extender. Nickel-free and hypoallergenic. Free worldwide DHL Express in 1-5 business days, with all import duties and taxes covered. 30-day “Love It or Return It” returns.
Is there a gold version, or matching studs?
Both. The same 21 mm flat chromosome pendant is available in 18K gold vermeil at the same chain length. Matching flat chromosome studs exist in sterling silver. The round chromosome necklace also exists in both silver and gold vermeil for buyers who prefer the metaphase form over the karyotype shape.
