dbSNP rs755085146: TSR1:p.Pro744Ser (chr17-2324510-G-A) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS2

The NM_018128.5(TSR1):c.2230C>T(p.Pro744Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0000062 in 1,614,046 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P744T) has been classified as Uncertain significance.

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.
