Genes affected

RASEF (HGNC:26464): (RAS and EF-hand domain containing) This gene is a member of the Rab family of GTPases that are involved in regulation of membrane traffic. The encoded protein contains an N-terminal EF-hand domain, a coiled-coil motif and a C-terminal Rab domain. A potential role as tumor suppressor has been indicated for this gene.

The c.1585G>A (p.V529I) alteration is located in exon 12 (coding exon 12) of the RASEF gene. This alteration results from a G to A substitution at nucleotide position 1585, causing the valine (V) at amino acid position 529 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
