Homo sapiens

Also known as PIG2; CCDS2; TP53I2; HEL-S-20

Gene ID: 2593 | Gene type: protein coding

About GAMT

Cytogenetic location: 19p13.3 Genomic coordinates (GRCh38): 19:1,397,026-1,401,542 (from NCBI)

This gene has 5 transcripts (splice variants), 196 orthologues and is associated with 3 phenotypes. Broad expression in liver (RPKM 37.8), pancreas (RPKM 12.2) and 15 other tissues.

Summary

The protein encoded by this gene is a methyltransferase that converts guanidoacetate to creatine, using S-adenosylmethionine as the methyl donor. Defects in this gene have been implicated in neurologic syndromes and muscular hypotonia, probably due to creatine deficiency and accumulation of guanidinoacetate in the brain of affected individuals. Two transcript variants encoding different isoforms have been described for this gene. Pseudogenes of this gene are found on chromosomes 2 and 13. [provided by RefSeq, Feb 2012]
