Genotype–Phenotype Association in ABCA4-Associated Retinopathy
Stargardt disease (STGD1) is the most common inherited retina degeneration. It is caused by biallelic ABCA4 variants, and no treatment is available... -
Beyond Mendelian Inheritance: Genetic Buffering and Phenotype Variability
Understanding the way genes work amongst individuals and across generations to shape form and function is a common theme for many genetic studies....

Reactive Microglia and Astrocyte Phenotype Transitions: A Framework
This chapter gives an overview of the reactions of microglia and astrocytes to pathological events. In the focus are the microglia as they are... -
Neuropsychological Genotype–Phenotype in Patients with Williams Syndrome with Atypical Deletions: A Systematic Review
Williams syndrome (WS) is a neurodevelopmental disorder caused by a microdeletion in the q11.23 region of chromosome 7. Recent case series reports...

Genotype–phenotype correlation in PRKN-associated Parkinson’s disease
Bi-allelic pathogenic variants in PRKN are the most common cause of autosomal recessive Parkinson’s disease (PD). 647 patients with PRKN -PD were...

Differences in DNA methylation status explain phenotypic variability in patients with 5p− syndrome
Cri Du Chat syndrome, or 5p− syndrome, is characterized by a terminal or interstitial deletion on the short arm of chromosome 5 that causes variable...
