RPS2

Chr 16

ribosomal protein S2

Also known as: LLREP3, S2, uS5

RPS2 encodes a ribosomal protein that is an essential component of the 40S ribosomal subunit and plays a critical role in protein synthesis and ribosome assembly. This gene is highly constrained against loss-of-function variants (pLI 0.85, LOEUF 0.45), reflecting its fundamental importance for cellular function. Mutations in RPS2 cause developmental delays, intellectual disability, and growth retardation, typically following an autosomal dominant inheritance pattern.
