Researchers have identified MDGA2 as a causative gene for developmental and epileptic encephalopathy (DEE), a rare neurological disorder. The study highlights the potential for early diagnosis and new therapies to modulate MDGA2 function or reduce excessive excitatory signaling in the brain.
A new study found that Kirtland's warblers have exceptionally long runs of homozygosity (ROH) indicating very recent inbreeding, while also having a high frequency of potentially damaging genetic variants. This suggests that continued management is necessary to ensure the species' survival.
A high-resolution map of Arab and Middle Eastern population genetics has been unveiled, providing new insights into human history in the region. The study revealed that ancient populations in the Arabian Peninsula played a central role in early human migration out of Africa.
A genetic study found a DVL2 gene defect associated with screw tail and caudal vertebral anomalies in various dog breeds. The variant affects muzzle length and heart development, highlighting the importance of genetic testing for health problems.
A study by Kazan Federal University's Gene and Cell Technology Lab found a link between the CCR5 genotype and susceptibility to HFRS in Tatarstanis. Patients with the homozygous genotype had a longer oliguric phase and lower platelet count compared to those with the heterozygous genotype.
A combination therapy with PCSK9-inhibitors and lipoprotein-apheresis (LA) is proposed as a potential treatment for Homozygous Familial Hypercholesterolaemic (HoFH) patients. LA has potent therapeutic effects on inflammation and related mediators.
A recent study published in BMC Genomics has identified a gene mutation responsible for high juvenile mortality in calves. The mutation affects the structure of cilia in airways, leading to chronic infections and respiratory disease.
A recent study by the University of Leicester has discovered a potential link between recessively inherited DNA sequences and heart disease. The research found that individuals with Coronary Artery Disease (CAD) had higher levels of genome-wide homozygosity, which is associated with an increased risk of CAD. The study's findings sugges...
A new study analyzed DNA from over 2,100 children with autism and found evidence of a recessive, inherited genetic contribution in cases with significant intellectual disability. The research suggests that runs of homozygosity, or long strands of identical DNA, may harbor deleterious variants that increase disease susceptibility.
Researchers at the University of Bonn have decoded a possible mechanism for hybrid corn's high yield, finding that more genes are active in hybrid plants than in their homozygous parental lines. This increase in gene activity could lead to increased growth and vigor in hybrids.
Mipomersen significantly lowers LDL cholesterol levels by 24.7%, providing a new therapeutic strategy for inherited high cholesterol. The treatment also improves HDL cholesterol and reduces cardiovascular risk factors, making it a valuable addition to existing treatments.
A 30-year-old man died of variant Creutzfeldt-Jakob disease (vCJD) with a unique genetic profile, highlighting potential cases with long incubation periods. His heterozygous PRNP gene may indicate silently infected individuals, posing concerns for public health.
Researchers investigated germline homozygosity in patients with solid tumors, finding high frequencies of this characteristic associated with increased cancer risk. The study suggests that germline homozygosity at specific loci may contribute to cancer predisposition and could be considered in future cancer risk assessments.
Researchers investigated XPD allele interactions using compound heterozygote mice, finding that combinations of mutant alleles alleviated disease symptoms and improved gene function. This challenges the existing monoallelic paradigm, suggesting biallelic effects may occur in some patients.
Researchers found that individuals carrying the Epsilon4 allele showed reduced activation in the medial temporal lobe of the brain. This suggests that these individuals may be at risk for Alzheimer's disease and could potentially benefit from early interventions designed to delay or prevent its onset.
A large DNA-based study revealed that only a small percentage of people with the genetic mutation for hereditary hemochromatosis develop symptoms. Most individuals with the mutation remain asymptomatic and do not experience the disease's life-shortening effects.
Researchers found that bisexual and homosexual Caucasian men with one copy of the delta-32 mutation have a 70% reduced risk of HIV infection compared to those without the mutation. The study, published in the Journal of Acquired Immune Deficiency Syndromes, provides insight into resistance to HIV infection among high-risk populations.
