Global Impact: Unveiling the Prevalence of Rare Genetic Disorders

Researchers at the Children's Hospital of Philadelphia have identified a new genetic disorder that causes neurodevelopmental differences and abnormalities in the head, facial bones, and limbs. The disorder is believed to be caused by rare variants in the MAP4K4 gene, which is involved in signaling pathways related to normal cell growth. The researchers created a zebrafish model to confirm the gene's role in the disorder and suggest that it may be a valuable therapeutic target for other disorders as well. However, therapeutic interventions targeting MAP4K4 need to strike a balance between treating the disorder and avoiding an increased risk of cancer.

Improving rare variant association analyses with adjusted polygenic scores.

Adjusting for common variant polygenic scores can improve the yield in rare variant association analyses, according to a study using data from the UK Biobank. The researchers found that incorporating polygenic scores into the analysis increased the power to detect rare variant associations, particularly for traits with a strong polygenic component. The study highlights the importance of considering both common and rare genetic variation in association analyses and provides a resource for researchers to access the data and code used in the study.
