Nuclear speckle splicing regulatory protein 1 is a protein that in humans is encoded by the NSRP1 gene. ^{[5] [6]}

NSRP1 is located within nuclear speckles. ^[7] Speckles are dynamic membrane-less organelles within the nucleus and are rich in RNA splicing factors. ^[8] NSRP1 interacts with other splicing factors including SRSF1 and SRSF2 and modulates pre-mRNA splicing. ^{[7] [9]} Knockout of the mouse ortholog Nsrp1 resulted in early embryonic lethality. ^[7]

Humans with biallelic pathogenic variants in NSRP1 have an autosomal recessive condition called neurodevelopmental disorder with spasticity, seizures, and brain abnormalities (NEDSSBA, MIM 620001). ^{[10] [11]} Affected individuals have delayed developmental milestones, axial hypotonia, appendicular spasticity, epilepsy, and often microcephaly. Brain abnormalities including under-opercularization, cerebellar atrophy, and thinning of the corpus callosum can be seen. Patients with NEDSSBA often have a clinical diagnosis of spastic cerebral palsy (CP), ^[10] and thus NEDSSBA should be considered a CP disease gene.
