Genes affected

SPAG9 (HGNC:14524): (sperm associated antigen 9) This gene encodes a member of the cancer testis antigen gene family. The encoded protein functions as a scaffold protein that structurally organizes mitogen-activated protein kinases and mediates c-Jun-terminal kinase signaling. This protein also binds to kinesin-1 and may be involved in microtubule-based membrane transport. This protein may play a role in tumor growth and development. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2011]

The c.3133C>T (p.R1045W) alteration is located in exon 25 (coding exon 25) of the SPAG9 gene. This alteration results from a C to T substitution at nucleotide position 3133, causing the arginine (R) at amino acid position 1045 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
