According to a study conducted by researchers at Brock University, Canada, and published in the (http://www.pnas.org/content/early/2017/12/05/1705895114) journal PNAS on Monday, Y-linked protein gets into the bloodstream of some women when they are pregnant with a boy.
With reference to genotype on a single locus, there are twenty five different parent unions possible in nuclear pedigrees, six for each of autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive (6+6+6+6 = 24) and one for Y-linked inheritance pattern.
Background: The human Ubiquitously transcribed tetratricopeptide repeat gene, Y-linked (UTY) gene encodes histone demethylase involved in protein-protein interactions.
No significant diseases are related to Y chromosome abnormalities, but having hairy ears is a trait thought to be determined by a Y-linked gene.
The findings suggest that because these Y-linked genes are active across the body, they may actually be contributing to differences in disease susceptibility and severity observed between men and women.
For example, a DM-domain transcription factor on the Y chromosome (DMY) has been identified as the master gene in medaka fish (Oryzias latipes) [5, 6]; Y-linked anti-Mullerian hormone (amh) initiates the onset of sex differentiation in Odontesthes hatcheri [7]; and a sex-linked polymorphism of amh receptor (amhr2) is responsible for male development in Takifugu rubripes [8].
Further improvement was made by designing a qPCR assay for the repetitive DYS14 sequence located in the TSPY1 (testis-specific protein, Y-linked 2), TSPY2 (testis-specific protein, Y-linked 2), and TSPY3 (testis-specific protein, Y-linked 3) gene region (hereafter referred to as the DYS assay), which produced an approximately 10-fold increase in sensitivity (3).
