Caprin-1 is a protein that in humans is encoded by the CAPRIN1 gene.[5][6][7][8][9][10] It is suggested that Caprin1 (a.k.a. RNG105) is essential for the formation of long-term memory.[11]

Clinical significance

edit

In 2022, loss-of-function mutations of the CAPRIN1 gene were shown to result in an autosomal-dominant disorder. Patients having the newly-discovered disorder suffer from language impairment, speech delay, intellectual disability, ADHD and autism spectrum disorder.[12] Somatically, they have respiratory problems, limb/skeletal anomalies, developmental delay, feeding difficulties, seizures and ophthalmologic problems.
