Genes affected

RGPD3 (HGNC:32416): (RANBP2 like and GRIP domain containing 3) This gene is located in a cluster of Ran-binding protein related genes on chromosome 2 which arose through duplication in primates. The encoded protein contains an N-terminal TPR (tetratricopeptide repeat) domain, two Ran-binding domains, and a C-terminal GRIP domain (golgin-97, RanBP2alpha, Imh1p and p230/golgin-245) domain.

The c.5054A>G (p.E1685G) alteration is located in exon 21 (coding exon 21) of the RGPD3 gene. This alteration results from a A to G substitution at nucleotide position 5054, causing the glutamic acid (E) at amino acid position 1685 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
