Genes affected

SARS1 (HGNC:10537): (seryl-tRNA synthetase 1) This gene belongs to the class II amino-acyl tRNA family. The encoded enzyme catalyzes the transfer of L-serine to tRNA (Ser) and is related to bacterial and yeast counterparts. Multiple alternatively spliced transcript variants have been described but the biological validity of all variants is unknown. [provided by RefSeq, Jul 2010]

SARS1 Gene-Disease associations (from GenCC):

• hereditary peripheral neuropathy

  Inheritance: AD Classification: STRONG Submitted by: PanelApp Australia
