Ode to the X Chromosome

You may not learn cutting-edge science from this New York Times article, but anyone who's had to do genetics may enjoy the ode to the X chromosome. GTO learned, for instance, that the chromosome was named X not for its shape but because its mechanism within the genome was considered an unknown. Reporter Natalie Angier writes, "It is a supple, switchbacking, multitasking gumby doll patch of the genome; and the closer you look, the more Cirque du Soleil it appears." You can check out the full character assessment of the X chromosome here.

 

The Scan

Myotonic Dystrophy Repeat Detected in Family Genome Sequencing Analysis

While sequencing individuals from a multi-generation family, researchers identified a myotonic dystrophy type 2-related short tandem repeat in the European Journal of Human Genetics.

TB Resistance Insights Gleaned From Genome Sequence, Antimicrobial Response Assays

Researchers in PLOS Biology explore M. tuberculosis resistance with a combination of sequencing and assays looking at the minimum inhibitory concentrations of 13 drugs.

Mendelian Disease Genes Prioritized Using Tissue-Specific Expression Clues

Mendelian gene candidates could be flagged for further functional analyses based on tissue-specific transcriptome and proteome profiles, a new Journal of Human Genetics paper says.

Single-Cell Sequencing Points to Embryo Mosaicism

Mosaicism may affect preimplantation genetic tests for aneuploidy, a single-cell sequencing-based analysis of almost three dozen embryos in PLOS Genetics finds.
