Genes affected

RASSF8 (HGNC:13232): (Ras association domain family member 8) This gene encodes a member of the Ras-assocation domain family (RASSF) of tumor suppressor proteins. This gene is essential for maintaining adherens junction function in epithelial cells and has a role in epithelial cell migration. It is a lung tumor suppressor gene candidate. A chromosomal translocation t(12;22)(p11.2;q13.3) leading to the fusion of this gene and the FBLN1 gene is found in a complex type of synpolydactyly. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2011]

The c.820G>A (p.A274T) alteration is located in exon 3 (coding exon 2) of the RASSF8 gene. This alteration results from a G to A substitution at nucleotide position 820, causing the alanine (A) at amino acid position 274 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
