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 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.19609547).

Ambry Genetics

Oct 17, 2023

The c.88A>G (p.T30A) alteration is located in exon 2 (coding exon 2) of the GSE1 gene. This alteration results from a A to G substitution at nucleotide position 88, causing the threonine (T) at amino acid position 30 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
