Genes affected

TSR1 (HGNC:25542): (TSR1 ribosome maturation factor) Enables RNA binding activity. Predicted to be involved in endonucleolytic cleavage of tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) and maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Predicted to be located in nucleolus. Predicted to be part of preribosome, small subunit precursor. [provided by Alliance of Genome Resources, Apr 2022]

TSR1 links:

SRR (HGNC:14398): (serine racemase) Enables several functions, including L-serine ammonia-lyase activity; PDZ domain binding activity; and anion binding activity. Involved in pyruvate biosynthetic process; response to lipopolysaccharide; and serine family amino acid metabolic process. Located in cytoplasm and neuronal cell body.

Ambry Genetics

Jul 09, 2021

The c.2117T>C (p.I706T) alteration is located in exon 13 (coding exon 13) of the TSR1 gene. This alteration results from a T to C substitution at nucleotide position 2117, causing the isoleucine (I) at amino acid position 706 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
