Genes affected

TSR3 (HGNC:14175): (TSR3 ribosome maturation factor) Enables transferase activity. Involved in enzyme-directed rRNA pseudouridine synthesis. Predicted to be located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

TSR3 links:

BAIAP3 (HGNC:948): (BAI1 associated protein 3) This p53-target gene encodes a brain-specific angiogenesis inhibitor. The protein is a seven-span transmembrane protein and a member of the secretin receptor family. It interacts with the cytoplasmic region of brain-specific angiogenesis inhibitor 1. This protein also contains two C2 domains, which are often found in proteins involved in signal transduction or membrane trafficking. Its expression pattern and similarity to other proteins suggest that it may be involved in synaptic functions. Several transcript variants encoding different isoforms have been found for this gene.

The c.833G>A (p.G278E) alteration is located in exon 6 (coding exon 6) of the TSR3 gene. This alteration results from a G to A substitution at nucleotide position 833, causing the glycine (G) at amino acid position 278 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
