Researchers at IDIBELL and ICO aim to study pathogenicity of variants in DNA repair genes MSH2 and MSH6. The funding will improve molecular diagnostics of Lynch syndrome, enabling better risk assessment and prevention measures.
A recent study discovered that a PSMB8 gene mutation causes Japanese autoinflammatory syndrome with lipodystrophy. The researchers identified the specific mechanism of the mutation and its impact on human health.
A study of 40 North American and European patients with Costello syndrome found that mutations in the HRAS gene sequence were present in 82.5% of cases, primarily affecting codon 12 or 13. The research suggests a paternal origin for the mutations and provides hope for targeted cancer treatment.
A new genetic test has been found to detect mutations that conventional DNA tests may miss, particularly large genomic deletions. This test, known as conversion analysis, increased the diagnostic yield of deleterious mutations by 56%. The study suggests this method could be a valuable addition to current genetic testing strategies.
Researchers developed an easy and affordable way to screen families for underlying genetic mutations that predispose them to developing breast cancer. The new test can indicate the presence of mutations in breast cancer genes in 50% of cases, potentially even more.
Researchers found a gene crucial for roundworm mating strongly resembles a gene involved in human polycystic kidney disease. The study uses Caenorhabditis elegans to understand the role of genes controlling reproductive behaviors, potentially shedding light on PKD1's function and its connection to kidney disease.
A new study uses computational tools to track human cancer development, suggesting that adenoma and carcinoma lines can arise from a common precursor but develop in parallel. This challenges the conventional model of cancer progression, which assumes a linear process from normal cell to polyp to cancer.
Scientists have identified eight genes necessary for vertebrate sensory hair cell function in a study of zebrafish mutants with balance problems. These genes are specifically involved in the production of extracellular potential generation, a key measure of hair cell function.
