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.

Ambry Genetics

Sep 29, 2023

The c.173G>A (p.R58H) alteration is located in exon 3 (coding exon 2) of the SRR gene. This alteration results from a G to A substitution at nucleotide position 173, causing the arginine (R) at amino acid position 58 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
