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]

RUFY1-AS1 (HGNC:40903): (RUFY1 antisense RNA 1)

LOC128966623 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (REVEL=0.061).
• BP7: Synonymous conserved (PhyloP=0.409 with no splicing effect.
