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 Benign. Variant got -10 ACMG points.

• BP6: Variant X-129539986-TA-T is Benign according to our data. Variant chrX-129539986-TA-T is described in ClinVar as [Likely_benign]. Clinvar id is 1205397.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00452 (493/108967) while in subpopulation AFR AF= 0.0148 (442/29899). AF 95% confidence interval is 0.0136. There are 2 homozygotes in gnomad4. There are 133 alleles in male gnomad4 subpopulation. Median coverage is 21. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 2 XL gene
