First Complete Sequence of a Human Y Chromosome

An international research team has generated the first truly complete sequence of a human Y chromosome, the final human chromosome to be fully sequenced. The new sequence, which fills in gaps across more than 50% of the Y chromosome’s length, uncovers important genomic features with implications for fertility, such as factors in sperm production. The study, led by the Telomere-to-Telomere (T2T) Consortium, a team of researchers funded by the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, was published on August 23, 2023 in Nature. The article is titled “The Complete Sequence of a Human Y Chromosome.”
