A restricted role for sperm borne micro RNAs in mammalian fertilization. Repping Set al. Ubiquitously transcribed tetratricopeptide repeat containing, Y-encoded UTY In human, thesix mRNA transcripts of UTY gene translate into the enzyme histone demethylase UTY that contains tetra-trico-peptide repeats and are thought to be involved in protein-protein interactions.
S, Torgersen K. A large expansion of the HSFY gene family in cattle shows dispersion across Yq and testis-specific expression.
Hum Reprod Update. Although the small sample size precluded the use of association tests, this sample could largely be considered as similar to a standard Y-haplogroup distribution of the studied population. Duplications of azfc deletion y-chromosome sex linked traits in Buffalo AZFa region of the human Y chromosome are mediated by homologous recombination between HERVs and are compatible with male fertility.
Accordingly, several partial AZFc deletions resulting from recombination between internal AZFc amplicons have already been described [ 12 — 16 ]. Genomic heterogeneity and instability of the AZF locus on the human Y chromosome.
Nat Genet Ann Hum Genet. Partial deletions in the AZFc region of the Y chromosome occur in men with impaired as well as normal spermatogenesis. Contact us Submission enquiries: Access here and click Contact Us General enquiries: info biomedcentral.
In our data, after removing TSPYthe most variable gene family fig. Giachini Cet al. S, Gupta A. Sex determination and gonadal development in mammals. Each of the sex-chromosomes harbor one amelogenin gene.
Recently, gene conversion on the human Y was found to be biased towards ancestral alleles and towards GC Skov et al. It is yet unclear whether some other defects co-exist, which may have further impact on sperm function and ultimately the fertilization process.
We further tested whether ampliconic gene copy number is associated with two sexually dimorphic traits, namely height and FMF see Materials and Methods.
