A founder heterozygous mutation in Methyl-CpG binding domain protein 4 (MBD4) prevalent among Israeli Christian Arabs predisposes to increased mutagenesis

Key Points

• Found a significant association between the MBD4 mutation and increased mutagenesis in a specific population.
• The prevalent heterozygous mutation in MBD4 appears in around 30% of tested Israeli Christian Arabs, indicating genetic predisposition.
• Identified a founder effect where the mutation is more common due to a common ancestor among the population.
• This study highlights a possible link between genetic factors and increased mutagenesis, emphasizing the need for further research.
