Genes affected

RASSF1 (HGNC:9882): (Ras association domain family member 1) This gene encodes a protein similar to the RAS effector proteins. Loss or altered expression of this gene has been associated with the pathogenesis of a variety of cancers, which suggests the tumor suppressor function of this gene. The inactivation of this gene was found to be correlated with the hypermethylation of its CpG-island promoter region. The encoded protein was found to interact with DNA repair protein XPA. The protein was also shown to inhibit the accumulation of cyclin D1, and thus induce cell cycle arrest. Several alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. [provided by RefSeq, May 2011]

The c.883G>A (p.A295T) alteration is located in exon 6 (coding exon 6) of the RASSF1 gene. This alteration results from a G to A substitution at nucleotide position 883, causing the alanine (A) at amino acid position 295 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
