Genes affected

PAG1 (HGNC:30043): (phosphoprotein membrane anchor with glycosphingolipid microdomains 1) The protein encoded by this gene is a type III transmembrane adaptor protein that binds to the tyrosine kinase csk protein. It is thought to be involved in the regulation of T cell activation. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.710G>A (p.R237H) alteration is located in exon 7 (coding exon 4) of the PAG1 gene. This alteration results from a G to A substitution at nucleotide position 710, causing the arginine (R) at amino acid position 237 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
