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.1943C>T (p.P648L) alteration is located in exon 15 (coding exon 15) of the RASEF gene. This alteration results from a C to T substitution at nucleotide position 1943, causing the proline (P) at amino acid position 648 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
