Genes affected

TAGAP (HGNC:15669): (T cell activation RhoGTPase activating protein) This gene encodes a member of the Rho GTPase-activator protein superfamily. The encoded protein may function as a Rho GTPase-activating protein. Alterations in this gene may be associated with several diseases, including rheumatoid arthritis, celiac disease, and multiple sclerosis. Alternate splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2013]

The c.1906C>G (p.P636A) alteration is located in exon 10 (coding exon 9) of the TAGAP gene. This alteration results from a C to G substitution at nucleotide position 1906, causing the proline (P) at amino acid position 636 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
