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]
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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.2309A>G (p.Y770C) alteration is located in exon 15 (coding exon 15) of the TSR1 gene. This alteration results from a A to G substitution at nucleotide position 2309, causing the tyrosine (Y) at amino acid position 770 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
