Article Synopsis
- Researchers studied mutations in a gene that affects a key protein involved in cell signaling, which is linked to severe health issues like impaired immunity in patients.
- The mutations were found to disrupt normal cell behavior by promoting excessive cell growth and responses to immune signals, specifically T cell receptor stimulation.
- The mutant protein was shown to interfere with a regulatory protein, leading to heightened activity of important signaling pathways that contribute to cell growth and survival.
Article Synopsis
- Fibrodysplasia Ossificans Progressiva (FOP) is a rare genetic disorder that often presents with congenital great toe abnormalities (CBHV), intermittent swelling, and abnormal bone growth.
- A case report describes a three-month-old girl with CBHV whose condition raised concerns for FOP, but comprehensive genetic testing revealed no typical markers for the disorder.
- The findings emphasize the importance of CBHV as an early diagnostic sign for FOP, while also suggesting that affected infants should be carefully evaluated and monitored before confirming a diagnosis.
Article Synopsis
- This study investigates the role of inversions—structural variants that involve the rearrangement of DNA—in genetic diseases, using data from 33,924 families involved in the 100,000 Genomes Project.
- Researchers identified 47 ultra-rare rearrangements, including de novo inversions, in genes linked to disease, with analyses correlating genetic findings to clinical outcomes in some cases, including a specific diagnosis for three family members.
- The findings suggest that while inversions are less common in genetic diseases compared to other structural variants, they can significantly contribute to the etiology in approximately 1 in 750 families with rare conditions.
Article Synopsis
- Whole genome sequencing (WGS) is being increasingly used to diagnose rare diseases, but traditional methods often have low diagnostic yields, typically 25-30%.
- In a study involving 122 rare disease patients and their relatives, a comprehensive bioinformatics approach led to a diagnostic yield of 35%, with 39% solved when including novel gene candidates.
- The study also identified several novel genes, expanded the phenotypic understanding of existing conditions, and resulted in critical changes to clinical diagnoses and treatments for some patients.
Article Synopsis
- A patient from the 100,000 Genomes Project was identified with a complex genetic variant in the KMT2E gene, which causes O'Donnell-Luria-Rodan syndrome.
- This case adds new information to the list of genetic mutations associated with this syndrome.
- It emphasizes the need to re-evaluate previously unexplained cases with improved tools for analyzing structural variants and updated genetic testing panels.
PKDCC encodes a component of Hedgehog signalling required for normal chondrogenesis and skeletal development. Although biallelic PKDCC variants have been implicated in rhizomelic shortening of limbs with variable dysmorphic features, this association was based on just two patients. In this study, data from the 100 000 Genomes Project was used in conjunction with exome sequencing and panel-testing results accessed via international collaboration to assemble a cohort of eight individuals from seven independent families with biallelic PKDCC variants.

The first individuals ascertained carried de novo loss-of-function (LoF) variants in HNRNPK. Here, we report 32 individuals with AKS (26 previously unpublished), including 13 with de novo missense variants.
View Article and Find Full Text PDFADP-ribosylation by ADP-ribosyltransferases (ARTs) has a well-established role in DNA strand break repair by promoting enrichment of repair factors at damage sites through ADP-ribose interaction domains. Here, we exploit the simple eukaryote Dictyostelium to uncover a role for ADP-ribosylation in regulating DNA interstrand crosslink repair and redundancy of this pathway with non-homologous end-joining (NHEJ). In silico searches were used to identify a protein that contains a permutated macrodomain (which we call aprataxin/APLF-and-PNKP-like protein; APL).
