The shortest bi-weekly genomics research report in the world. Curated by the Emedgene Research Division.
A deletion in the noncoding region reveals a gene that is critical for intestinal function. Researchers studied 8 infants with intractable congenital diarrhea from 7 unrelated families, where a previous WES yielded no results. WGS identified a common deletion region on chromosome 16 that they called the intestine-critical region (ICR). Mouse models support the discovery.
In this WGS study, a recessively inherited intronic repeat expansion in RFC1 was identified in 18 out of 22 CANVAS-affected families.
MNVs anyone? An evaluation of their functional impact and contribution to disease, using data from 6688 exomes. MNVs were found to be more damaging than SNVs even when both induce missense changes.
RNA sequencing data captured 16 time points during the differentiation of induced pluripotent stem cells to cardiomyocytes, in 19 human cell lines. Hundreds of dynamic eQTLs identified that change over time, including some that only affect intermediate stages of differentiation, and cannot be found by using data from mature tissues.
Improving the diagnostic yield of exome sequencing using RNA-seq data to predict gene–phenotype associations. Found novel genes for 10 out of 61 unsolved rare disease cases.
Screening the effects of 5.9 million SNPs on enhancer and promoter activity, the researchers identified more than 30,000 SNPs that alter the activity of putative regulatory elements.

A new deep-learning model can predict from a mammogram if a patient is likely to develop breast cancer as much as five years in the future. Using information from more than 90,000 mammograms, the model detected patterns too subtle for the human eye to detect.
Fetal WES yield is high after abnormal ultrasound in families with relevant history, and when US has abnormal brain, renal or musculoskeletal findings.
Frontiers in Genetics
Back to diversity
Large-scale multi-ethnic biobanks and population studies can provide new opportunities for genomic discovery and a better understanding of population disease risk.
Nature Reviews Genetics
And these new population-specific studies:
- Germline pathogenic variants reported in Japanese patients with prostate cancer a Journal of the Cancer Institute
- GWAS of QRS duration identifies new loci specific to Hispanic/Latino populations PLOS One
- T2D in 433,540 East Asian individuals bioRxiv
Back to reanalysis
MedSeq examined the effort and value of reanalysis for monogenic diseases, PGX and polygenic scores. 14 variants were reclassified and, upon reanalysis, 18 new variants met criteria for reporting, highlighting the need for periodic reanalysis.
Somatic mosaicism in normal tissues
Somatic mutations were detected in nearly all individuals and across many normal human tissues. Interestingly, the skin, lung, and esophagus exhibited the most mutations, suggesting that the environment generates many human mutations.

The first known case of autoimmune arthritis associated with a mutation in GATA3. This study expands the phenotypic spectrum of GATA3 mutations.
