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.907G>A (p.D303N) 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 907, causing the aspartic acid (D) at amino acid position 303 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
