Genes affected

RANBP9 (HGNC:13727): (RAN binding protein 9) This gene encodes a protein that binds RAN, a small GTP binding protein belonging to the RAS superfamily that is essential for the translocation of RNA and proteins through the nuclear pore complex. The protein encoded by this gene has also been shown to interact with several other proteins, including met proto-oncogene, homeodomain interacting protein kinase 2, androgen receptor, and cyclin-dependent kinase 11.

The c.1681G>A (p.V561I) alteration is located in exon 11 (coding exon 11) of the RANBP9 gene. This alteration results from a G to A substitution at nucleotide position 1681, causing the valine (V) at amino acid position 561 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
