Genome-wide association studies have identified as a Parkinson's disease (PD) risk locus, with a common missense variant p.Asp543Asn in the synaptic vesicle glycoprotein 2C (SV2C) protein significantly associated with PD. We examined if other rare variants also influence PD risk. We analyzed sequencing data of 9810 East Asian individuals comprising 4298 patients and 5512 controls and identified 55 rare nonsynonymous variants. There was no significant association of rare nonsynonymous or loss-of-function variants with PD. Our findings show that besides p.Asp543Asn, other rare coding variants in do not play a major role in PD susceptibility in East Asia.

Rare cancers, defined by an annual incidence of fewer than 6 per 100,000 cases, pose significant challenges due to their complexity, lack of expertise, and limited treatment options. In Bulgaria, these challenges are compounded by limited resources, fragmented care, and outdated policies. This study investigates policy stakeholder perspectives to identify gaps and propose policy alternatives for rare cancer care in Bulgaria, with implications for the broader European Union (EU) context.

The Mediator complex regulates protein-coding gene transcription by coordinating the interaction of upstream enhancers with the basal transcription machinery at the promoter. Pathogenic variants in Mediator subunits typically lead to neurodevelopmental or neurodegenerative disorders with variable clinical presentations, designated as MEDopathies. Here, we report the identification of 25 individuals from 18 families with bi-allelic MED16 variants who have a multiple congenital anomalies (MCAs)-intellectual disability syndrome.

Primary trimethylaminuria (TMAU) is characterized by systemic accumulation of trimethylamine (TMA) due to the deficient activity of flavin-containing monooxygenase 3 (FMO3). The disorder does not have detrimental pathophysiological consequences, but patients develop psychological symptoms due to the emotionally debilitating bodily odor defined as decaying fish that affects their quality of life. Here, we illustrate the utility of a diagnostic workup on an adolescent with primary TMAU, including biochemical and genetic investigations that confirm the diagnosis.
