Abstract excerpt
BACKGROUND: Developmental stuttering, a multifactorial speech disorder with remarkable rate of spontaneous recovery pose challenges for gene discoveries. Exonic variants in GNPTAB, GNPTG, and NAGPA involved in lysosomal pathway and AP4E1, IFNAR1, and ARMC3-signaling genes reported till date explain only ∼2.1% - 3.7% of persistent stuttering cases. AIM: We aimed to identify additional genetic determinants of...
