Genes affected

ZNF467 (HGNC:23154): (zinc finger protein 467) The protein encoded by this gene is a zinc finger protein whose function has not yet been elucidated in humans. However, the mouse ortholog of this protein enhances adipocyte differentiation and suppresses osteoblast differentiation in bone marrow. The mouse protein also is a transcription factor for several genes and can help recruit histone deacetylase complexes. [provided by RefSeq, Aug 2016]

SSPOP (HGNC:21998): (SCO-spondin, pseudogene) Predicted to enable peptidase inhibitor activity. Predicted to be involved in several processes, including cell adhesion; negative regulation of catalytic activity; and regulation of peptidase activity. Predicted to be located in cytoplasm. Predicted to be active in extracellular matrix and extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.83T>G (p.V28G) alteration is located in exon 2 (coding exon 2) of the SSPO gene. This alteration results from a T to G substitution at nucleotide position 83, causing the valine (V) at amino acid position 28 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
