In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars).

• Frequency: Genomes: not found (cov: 32)
• Consequence: UBIAD1 NM_013319.3 missense
• Clinical Significance: Pathogenic no assertion criteria provided P:1
• Conservation: PhyloP100: 0.137

Genes affected

UBIAD1 (HGNC:30791): (UbiA prenyltransferase domain containing 1) This gene encodes a protein thought to be involved in cholesterol and phospholipid metabolism. Mutations in this gene are associated with Schnyder crystalline corneal dystrophy. [provided by RefSeq, Oct 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.984
• PP5: Variant 1-11273886-A-G is Pathogenic according to our data. Variant chr1-11273886-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 858.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr1-11273886-A-G is described in Lovd as [Pathogenic].
