genetics

Scientists at Johns Hopkins Medicine say they have discovered how a group of proteins linked to Parkinson’s disease and amyotrophic lateral sclerosis act as “guardians” of mitochondria, small organelles, or subunits, within a cell that make and store energy and are found in almost all plants and animals.

Using patient data from several banks of genomics data, researchers at UC San Diego were able to make similar predictions of aging using either mutations or epigenetic modifications. Their results reveal a common link between two separate but equally prominent theories of aging.

Genomic analysis of causal variants between bipolar disorder I (BD-I) and epilepsy. (A) Venn plot shows specific and shared variants. Genetic correlation (rg) was estimated via LDSC. (B) Manhattan plot of conjFDR results. Lead SNPs with the same allelic effect direction are in red; opposite directions are in black. (C) LocusZoom plots show genetic associations at the SP4 locus, with physical maps of known genes and LD defined by SNP rs9639379.

Researchers have formed a consortium called SSPsyGene with the shared objective of studying the genetic causes of neurodevelopmental and psychiatric disorders (NPD). Their focus is on 250 high-risk genes that may contribute to these conditions. In the project's initial phase, they tested 23 of these risk genes. The stem cell lines they generated from this research will be shared globally to aid other scientists in studying how these genes contribute to NPD.
