Purpose: We sought to evaluate outcomes for clinical management after a genetic diagnosis from the Deciphering Developmental Disorders study.
Methods: Individuals in the Deciphering Developmental Disorders study who had a pathogenic/likely pathogenic genotype in the DECIPHER database were selected for inclusion ( = 5010). Clinical notes from regional clinical genetics services notes were reviewed to assess predefined clinical outcomes relating to interventions, prenatal choices, and information provision.
Background And Objectives: Disorders of coenzyme Q (CoQ) biosynthesis comprise a group of 11 clinically and genetically heterogeneous rare primary mitochondrial diseases. We sought to delineate clinical, biochemical, and neuroimaging features of these disorders, together with outcomes after oral CoQ supplementation and the utility of peripheral blood mononuclear cell (PBMNC) CoQ levels in monitoring therapy.
Methods: This was a retrospective cohort study, registered as an audit at a specialist pediatric hospital (Registration Number: 3318) of 14 patients with genetically confirmed CoQ biosynthesis deficiency, including 13 previously unreported cases.
Defects in motile cilia, termed motile ciliopathies, result in clinical manifestations affecting the respiratory and reproductive system, as well as laterality defects and hydrocephalus. We previously defined biallelic variants causing and male infertility, mirroring the findings in mice. Here, we present clinical and genomic findings in five newly identified individuals from four unrelated families affected by -related disorder.

- 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.
Heterozygous, pathogenic CUX1 variants are associated with global developmental delay or intellectual disability. This study delineates the clinical presentation in an extended cohort and investigates the molecular mechanism underlying the disorder in a Cux1 mouse model. Through international collaboration, we assembled the phenotypic and molecular information for 34 individuals (23 unpublished individuals).
