Data on mutations and Clinical features in SCN1A or SCN2A gene

Area of Science:

• Genetics
• Neurology
• Molecular Biology

Background:

• Mutations in Sodium voltage-gated channel alpha subunit 1 (SCN1A) and Sodium voltage-gated channel alpha subunit 2 (SCN2A) genes are implicated in various human epilepsy disorders.
• Understanding these genetic variations is crucial for diagnosing and managing epilepsy.

Purpose of the Study:

• To present a dataset of variants and associated clinical features for SCN1A and SCN2A gene mutations.
• To identify and characterize novel mutations within these genes.
• To correlate specific mutations with diverse clinical phenotypes observed in epilepsy patients.

Main Methods:

• Compilation of a dataset encompassing 48 epilepsy cases.
• Detailed analysis of 33 SCN1A and 14 SCN2A mutations, including the identification of novel variants.
• Collection and documentation of comprehensive clinical data for each case.

Main Results:

• The dataset includes 48 cases with mutations in SCN1A and SCN2A.
• Identified 33 SCN1A mutations (22 novel) and 14 SCN2A mutations (11 novel).
• Collected extensive clinical data including seizure characteristics, EEG, MRI, treatment, and developmental outcomes.

Conclusions:

• The presented data highlights novel mutations in SCN1A and SCN2A.
• This dataset provides valuable insights into the genotype-phenotype correlations of SCN1A and SCN2A-related epilepsy.
• The findings can aid in understanding the spectrum of epilepsy disorders associated with these genes.
