Genes affected

GSE1 (HGNC:28979): (Gse1 coiled-coil protein) This gene encodes a proline-rich protein with coiled coil domains that may be a subunit of a BRAF35-HDAC (BHC) histone deacetylase complex. This gene may function as an oncogene in breast cancer and enhanced expression of the encoded protein has been observed in breast cancer patients. [provided by RefSeq, May 2017]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3421721).

The c.404T>G (p.V135G) alteration is located in exon 3 (coding exon 3) of the GSE1 gene. This alteration results from a T to G substitution at nucleotide position 404, causing the valine (V) at amino acid position 135 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
