Genes affected

RASSF2 (HGNC:9883): (Ras association domain family member 2) This gene encodes a protein that contains a Ras association domain. Similar to its cattle and sheep counterparts, this gene is located near the prion gene. Two alternatively spliced transcripts encoding the same isoform have been reported.

The c.919G>A (p.V307M) alteration is located in exon 12 (coding exon 10) of the RASSF2 gene. This alteration results from a G to A substitution at nucleotide position 919, causing the valine (V) at amino acid position 307 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
