Genes affected

RUFY3 (HGNC:30285): (RUN and FYVE domain containing 3) This gene encodes a RPIP8, UNC-14, and NESCA domain-containing protein that is required for maintenance of neuronal polarity. In addition, it has been implicated in mediation of gastric cancer cell migration and invasion via interaction with P21-activated kinase-1, which promotes its expression. The encoded protein localizes to F-actin-enriched invadopodia to induce formation of protrusions, thereby facilitating cell migration. Alternative splicing results in multiple transcript variants.

The c.1318A>G (p.I440V) alteration is located in exon 12 (coding exon 12) of the RUFY3 gene. This alteration results from a A to G substitution at nucleotide position 1318, causing the isoleucine (I) at amino acid position 440 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
