Genes affected

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. [provided by Alliance of Genome Resources, Apr 2022]

SRR links:

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]

The c.886C>G (p.Q296E) alteration is located in exon 8 (coding exon 7) of the SRR gene. This alteration results from a C to G substitution at nucleotide position 886, causing the glutamine (Q) at amino acid position 296 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
