Genes affected
SPSB2 (HGNC:29522): (splA/ryanodine receptor domain and SOCS box containing 2) This gene encodes a member of a subfamily of proteins containing a central SPRY (repeats in splA and RyR) domain and a C-terminal suppressor of cytokine signaling (SOCS) box. This protein plays a role in cell signaling. This gene is present in a gene-rich cluster on chromosome 12p13 in the vicinity of the CD4 antigen and triosephosphate isomerase genes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

The c.260G>T (p.G87V) alteration is located in exon 2 (coding exon 1) of the SPSB2 gene. This alteration results from a G to T substitution at nucleotide position 260, causing the glycine (G) at amino acid position 87 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
