Genes affected

RASSF6 (HGNC:20796): (Ras association domain family member 6) This gene encodes a member of the Ras-association domain family (RASSF). Members of this family form the core of a highly conserved tumor suppressor network, the Salvador-Warts-Hippo (SWH) pathway. The protein encoded by this gene is a Ras effector protein that induces apoptosis. A genomic region containing this gene has been linked to susceptibility to viral bronchiolitis. Alternative splicing results in multiple transcript variants and protein isoforms. [provided by RefSeq, Jul 2012]

The c.899T>C (p.F300S) alteration is located in exon 9 (coding exon 9) of the RASSF6 gene. This alteration results from a T to C substitution at nucleotide position 899, causing the phenylalanine (F) at amino acid position 300 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
