Insights

PRICKLE1 gene mutations cause developmental disorders. A new PRICKLE1 variant (p.Ala274Thr) is linked to early infantile epileptic encephalopathy and developmental arrest in a young boy.

Area of Science:

  • Genetics and Developmental Biology
  • Neuroscience

Background:

  • The PRICKLE1 gene encodes a key protein in planar cell polarity pathways, crucial for cell organization during human development.
  • Mutations in PRICKLE1 are associated with a spectrum of neurological disorders, including epilepsy, neural tube defects, and autism spectrum disorder.

Observation:

  • A novel variant in the PRICKLE1 gene (NM_153026.2:c.820G>A, resulting in p.Ala274Thr amino acid change) was identified.
  • This variant was observed in a young male patient exhibiting severe early infantile epileptic encephalopathy.

Findings:

  • The identified PRICKLE1 variant (p.Ala274Thr) represents a new genetic cause for early infantile epileptic encephalopathy.
  • This case highlights the critical role of PRICKLE1 in early neurodevelopment and brain function.

Implications:

  • Further research into PRICKLE1 variants can improve understanding and diagnosis of early-onset epileptic encephalopathies.
  • This finding expands the genotypic spectrum of PRICKLE1-associated neurodevelopmental disorders.
