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]

Ambry Genetics

May 23, 2023

The c.272G>C (p.G91A) 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 272, causing the glycine (G) at amino acid position 91 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
