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.1874G>A (p.C625Y) alteration is located in exon 14 (coding exon 14) of the RASEF gene. This alteration results from a G to A substitution at nucleotide position 1874, causing the cysteine (C) at amino acid position 625 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
