Genes affected

RUFY1 (HGNC:19760): (RUN and FYVE domain containing 1) This gene encodes a protein that contains a RUN domain and a FYVE-type zinc finger domain. The encoded protein binds to phosphatidylinositol-3-phosphate (PI3P) and plays a role in early endosomal trafficking, tethering and fusion through interactions with small GTPases including Rab4, Rab5 and Rab14. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]

The c.184T>C (p.W62R) alteration is located in exon 1 (coding exon 1) of the RUFY1 gene. This alteration results from a T to C substitution at nucleotide position 184, causing the tryptophan (W) at amino acid position 62 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
