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.5213C>T (p.T1738M) alteration is located in exon 22 (coding exon 22) of the RGPD3 gene. This alteration results from a C to T substitution at nucleotide position 5213, causing the threonine (T) at amino acid position 1738 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
