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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2023The c.3286G>A (p.A1096T) alteration is located in exon 26 (coding exon 26) of the SPAG9 gene. This alteration results from a G to A substitution at nucleotide position 3286, causing the alanine (A) at amino acid position 1096 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
