Genes affected

SART3 (HGNC:16860): (spliceosome associated factor 3, U4/U6 recycling protein) The protein encoded by this gene is an RNA-binding nuclear protein that is a tumor-rejection antigen. This antigen possesses tumor epitopes capable of inducing HLA-A24-restricted and tumor-specific cytotoxic T lymphocytes in cancer patients and may be useful for specific immunotherapy. This gene product is found to be an important cellular factor for HIV-1 gene expression and viral replication. It also associates transiently with U6 and U4/U6 snRNPs during the recycling phase of the spliceosome cycle. This encoded protein is thought to be involved in the regulation of mRNA splicing.

This variant was identified in an affected child in trans with a second variant in SART3 c.757C>T (compound heterozygous). This variant was inherited from a heterozgyous unaffected father. It was identified as part of a larger study that has found biallelic variants in SART3 in nine children from six families with overlapping clinical features. The variant falls in a highly conserved residue within an important RRM protein domain. The variant is extremely rare or absent in population databases. -
