“Our findings suggest that mtDNA haplogroups can play a role in Covid-19 pathogenesis, thus potentially useful in identifying susceptibility to its severe form.” #DNA #isogg #epigenetics #covid #mtDNA #mitochondria #haplogroups

“RNASeq analyses suggest Y-chromosome gene expression differs between brain and blood tissues but does not differ significantly in cases, controls or specific haplogroups. Overall, we did not find any strong associations between Y-chromosome genetics and Parkinson's disease, suggesting the explanation for the increased prevalence in males may lie elsewhere.” #isogg #dna #YDNA #Parkinsons #haplogroups #geneadons

Definitions 🧵:
A #haplogroup is a combination of #alleles that tend to be inherited together.
An #allele is a variation of the same sequence of nucleotides at the same place on a DNA molecule.

#Haplogroups pertain to a single line of descent. As such, individual membership of a haplogroup relies on a small proportion of the #genetic material possessed by that individual.

Mothers pass on mitochondrial #DNA unmixed to all their children; so the #ancestry can be traced along the maternal line.
