TSR1
Chr 17TSR1 ribosome maturation factor
The TSR1 protein is required for maturation of the 40S ribosomal subunit in the nucleolus through RNA binding and processing of ribosomal RNA transcripts. Mutations cause autosomal recessive intellectual disability with congenital malformations and dysmorphic facies, typically presenting in early infancy with developmental delays and distinctive facial features. This gene is highly intolerant to loss-of-function variants, reflecting its essential role in ribosome biogenesis.
