Genes affected

ARG2 (HGNC:664): (arginase 2) Arginase catalyzes the hydrolysis of arginine to ornithine and urea. At least two isoforms of mammalian arginase exists (types I and II) which differ in their tissue distribution, subcellular localization, immunologic crossreactivity and physiologic function. The type II isoform encoded by this gene, is located in the mitochondria and expressed in extra-hepatic tissues, especially kidney. The physiologic role of this isoform is poorly understood; it is thought to play a role in nitric oxide and polyamine metabolism. Transcript variants of the type II gene resulting from the use of alternative polyadenylation sites have been described. [provided by RefSeq, Jul 2008]

ARG2 links:

VTI1B (HGNC:17793): (vesicle transport through interaction with t-SNAREs 1B) Enables SNARE binding activity and chloride channel inhibitor activity. Involved in regulation of protein localization to plasma membrane. Located in several cellular components, including endosome membrane; lysosomal membrane; and perinuclear region of cytoplasm.

Ambry Genetics

Jan 30, 2024

The c.1054G>T (p.V352L) alteration is located in exon 8 (coding exon 8) of the ARG2 gene. This alteration results from a G to T substitution at nucleotide position 1054, causing the valine (V) at amino acid position 352 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
