[A familial brain malformation syndrome with symptomatic hypernatremia]

Area of Science:

• Neuroscience
• Genetics
• Pediatrics

Background:

• Cerebral malformations represent a diverse group of congenital brain abnormalities.
• Chronic hypernatremia can result from various factors, including neurological and genetic disorders.

Observation:

• Three children from a Moroccan family presented with microcephaly and frontal brain hypoplasia.
• Absence of the frontal lateral ventricles and midline defects with fused ventricles, resembling holoprosencephaly, were noted.
• Clinical symptoms included generalized spasticity, delayed mental development, and hypodipsia (reduced thirst).

Findings:

• A novel familial cerebral malformation syndrome is described.
• The condition is associated with significant neurodevelopmental deficits and chronic hypernatremia.
• Genetic etiology is suggested due to the familial occurrence.

Implications:

• This case highlights a potential new genetic syndrome affecting brain development and fluid balance.
• Understanding this malformation may offer insights into the genetic control of brain morphogenesis and osmoregulation.
• Further research is needed to identify the specific genetic mutations responsible.
