Genes affected
SPATA2 (HGNC:14681): (spermatogenesis associated 2) Enables signaling receptor complex adaptor activity and ubiquitin-specific protease binding activity. Involved in several processes, including protein deubiquitination; regulation of necroptotic process; and regulation of tumor necrosis factor-mediated signaling pathway. Located in cytoplasm; fibrillar center; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 26, 2024The c.1270G>A (p.A424T) alteration is located in exon 3 (coding exon 2) of the SPATA2 gene. This alteration results from a G to A substitution at nucleotide position 1270, causing the alanine (A) at amino acid position 424 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
