KHDRBS3
Chr 8KH RNA binding domain containing, signal transduction associated 3
Also known as: Etle, SALP, SLM-2, SLM2, T-STAR, TSTAR, etoile
The KHDRBS3 protein binds RNA and regulates alternative mRNA splicing, particularly of neurexins which are critical for synaptic function and targeting. Mutations cause autosomal recessive intellectual disability with variable features including developmental delay and neurological abnormalities. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.493), and its regulation of neurexin splicing at glutamatergic synapses explains the neurodevelopmental phenotype.
