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.5146G>A (p.V1716I) alteration is located in exon 22 (coding exon 22) of the RGPD3 gene. This alteration results from a G to A substitution at nucleotide position 5146, causing the valine (V) at amino acid position 1716 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
