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 GeneticsJan 26, 2023The c.3085G>T (p.V1029L) alteration is located in exon 24 (coding exon 24) of the SPAG9 gene. This alteration results from a G to T substitution at nucleotide position 3085, causing the valine (V) at amino acid position 1029 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
