A form of autosomal dominant retinitis pigmentosa (ADRP) mapping to chromosome 17p has been reported in a single large South African family. We now report a new family with severe early onset ADRP which maps to 17p. Linkage and haplotype analysis in this family places the ADRP locus in the 5 cM interval between markers AFMc024za5 and D17S1845, confirming the data obtained in the South African family. The discovery of a second 17p linked family may imply that this is one of the more common loci for dominant RP. In addition, the confirmation of an RP diagnosis at this locus is of interest since loci for a dominant cone dystrophy and Leber's congenital amaurosis (LCA1) have recently been linked to the same markers. While the cone dystrophy locus may be allelic with RP, our data and that of Goliath et al show that distinct genes are responsible for dominant RP and Leber's congenital amaurosis on chromosome 17p.

Autosomal dominant polycystic kidney disease (ADPKD) is the fourth leading cause of end-stage renal disease, contributing substantially to patient morbidity, mortality, and healthcare system strain. Emerging research highlights a pivotal role of epigenetics in ADPKD's pathophysiology, where mechanisms like DNA methylation, histone modifications, and non-coding RNA regulation significantly impact disease onset and progression. These epigenetic factors influence gene expression and regulate key processes involved in cyst formation and expansion, fibrosis, and inflammatory infiltration, thus accelerating ADPKD progression.

Background: Variants in the UQCRC1 gene have been proposed to cause autosomal dominant Parkinson's disease with neuropathy. However, definitive confirmation of UQCRC1 as an authentic Parkinson's gene remains elusive, as follow-up studies have not yet provided conclusive evidence.
Methods: 382 Austrian Parkinson's patients, particularly selected for familial and/or early onset cases, were Exome sequenced.

Background: Hereditary Angioedema is an autosomal dominant disorder caused by a lack or decrease in the function of the C1 inhibitor. It is a rare disease with low prevalence. Treatment focuses on symptom relief and short- and long-term prevention of acute attacks.

Background: A recent case report described an individual who was a homozygous carrier of the APOE3 Christchurch (APOE3ch) mutation and resistant to autosomal dominant Alzheimer's Disease (AD) caused by a PSEN1-E280A mutation. Whether APOE3ch contributed to the protective effect remains unclear.
Method: We generated a humanized APOE3ch knock-in mouse and crossed it to an amyloid-β (Aβ) plaque-depositing model.
