Global developmental delay (GDD) and intellectual disability (ID) affect up to 3% of the paediatric population, with a multifactorial aetiology that complicates genetic identification. To date, over 400 genes have been implicated in GDD. Here, we report a novel homozygous splice acceptor variant, NC_000001.

Introduction: Retinal dysfunction associated with CACNA2D4 gene defects is a rare disorder of photoreceptor to bipolar cell signaling. We report two affected siblings presenting a surprising disparity of retinal involvement.
Materials And Methods: Patients underwent complete ocular examination, multimodal fundus imaging, and full-field electroretinography (ffERG).

Hereditary ataxias are a highly heterogenous group of diseases characterized by loss of coordination. In this study, we investigated a family of random-bred dogs, in which two siblings were affected by a slowly progressive ataxia. They presented with clinical signs of progressive cerebellar ataxia, hypermetria, and absent menace response.
