Genes affected

GDI2 (HGNC:4227): (GDP dissociation inhibitor 2) GDP dissociation inhibitors are proteins that regulate the GDP-GTP exchange reaction of members of the rab family, small GTP-binding proteins of the ras superfamily, that are involved in vesicular trafficking of molecules between cellular organelles. GDIs slow the rate of dissociation of GDP from rab proteins and release GDP from membrane-bound rabs. GDI2 is ubiquitously expressed. The GDI2 gene contains many repetitive elements indicating that it may be prone to inversion/deletion rearrangements. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

Ambry Genetics

Mar 07, 2023

The c.213C>A (p.D71E) alteration is located in exon 3 (coding exon 3) of the GDI2 gene. This alteration results from a C to A substitution at nucleotide position 213, causing the aspartic acid (D) at amino acid position 71 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
