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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SPAG9. . Gene score misZ 3.1339 (greater than the threshold 3.09). Trascript score misZ 3.8344 (greater than threshold 3.09). GenCC has associacion of gene with schizophrenia.
BP4
Computational evidence support a benign effect (MetaRNN=0.16301537).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.3805A>G (p.M1269V) alteration is located in exon 29 (coding exon 29) of the SPAG9 gene. This alteration results from a A to G substitution at nucleotide position 3805, causing the methionine (M) at amino acid position 1269 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
