Genes affected

OCRL (HGNC:8108): (OCRL inositol polyphosphate-5-phosphatase) This gene encodes an inositol polyphosphate 5-phosphatase. This protein is involved in regulating membrane trafficking and is located in numerous subcellular locations including the trans-Golgi network, clathrin-coated vesicles and, endosomes and the plasma membrane. This protein may also play a role in primary cilium formation. Mutations in this gene cause oculocerebrorenal syndrome of Lowe and also Dent disease. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.42).
• BP6: Variant X-129540493-G-A is Benign according to our data. Variant chrX-129540493-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3001543.Status of the report is criteria_provided_single_submitter, 1 stars.
