Genes affected

AGXT2 (HGNC:14412): (alanine--glyoxylate aminotransferase 2) The protein encoded by this gene is a class III pyridoxal-phosphate-dependent mitochondrial aminotransferase. It catalyzes the conversion of glyoxylate to glycine using L-alanine as the amino donor. It is an important regulator of methylarginines and is involved in the control of blood pressure in kidney. Polymorphisms in this gene affect methylarginine and beta-aminoisobutyrate metabolism, and are associated with carotid atherosclerosis. Alternative splicing results in multiple transcript variants.

The c.824C>T (p.T275I) alteration is located in exon 8 (coding exon 8) of the AGXT2 gene. This alteration results from a C to T substitution at nucleotide position 824, causing the threonine (T) at amino acid position 275 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
