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]

The c.983A>G (p.Y328C) alteration is located in exon 3 (coding exon 2) of the SPATA2 gene. This alteration results from a A to G substitution at nucleotide position 983, causing the tyrosine (Y) at amino acid position 328 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
