Identification of novel FOXP1 variants in four unrelated patients with intellectual disability and speech impairment

Key Points

• Novel FOXP1 variants were identified, expanding the mutational spectrum associated with intellectual disability.
• Key evidence shows that in silico protein structure predictions help classify these variants, potentially aiding diagnosis.
• Assessment utilizing RNA analysis highlights the importance of understanding genetic variants related to speech impairment.
• Findings support broader applications of in silico methods in genetic variant classification, needing external validation.
