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.
Abstract:
The PRICKLE1 (Prickle Planar Cell Polarity Protein 1-MIM 608500) gene is involved in different phases of human development. The related diseases include autosomal recessive progressive myoclonus epilepsy - ataxia syndrome, neural tube defects associated with heterozygous mutations, agenesis of corpus callosum, polymicrogyria, and autistic spectrum disorder. Reported here is a young boy with a new variant (NM_153026.2:c.820G>A, p.Ala274Thr) presenting with an early infantile epileptic encephalopathy with developmental arrest.
