Expanding the genetic spectrum of neurogenetic disorders in Moroccan families by exome sequencing.

Exome sequencing of consanguineous Moroccan families — identification of pathogenic variants in known genes and novel candidate genes for NDD and neurodegenerative diseases

Exome sequencing is applied to consanguineous Moroccan families with neurogenetic disorders, identifying pathogenic variants in known genes and potentially novel candidate genes. North African populations are severely underrepresented in clinical genomics studies despite high consanguinity rates that facilitate rare recessive variant discovery. This work expands the accessible diagnostic genetic spectrum for this underserved population. ⚠️ Summary based on title (metadata verification needed).

Consanguineous North African families offer unique opportunities for recessive gene discovery: the high probability of homozygous-by-descent variants simplifies pathogenicity demonstration. Each exome study in these populations fills a real knowledge gap applicable to patients who often remain undiagnosed.
