Genes affected

TSPYL2 (HGNC:24358): (TSPY like 2) This gene encodes a member of the testis-specific protein Y-encoded, TSPY-like/SET/nucleosome assembly protein-1 superfamily. The encoded protein is localized to the nucleolus where it functions in chromatin remodeling and as an inhibitor of cell-cycle progression. This protein may play a role in the suppression of tumor growth. [provided by RefSeq, Sep 2009]

The c.561G>C (p.R187S) alteration is located in exon 1 (coding exon 1) of the TSPYL2 gene. This alteration results from a G to C substitution at nucleotide position 561, causing the arginine (R) at amino acid position 187 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
