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 9 ACMG points.

• PM1: In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_013319.3
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.993
• PP5: Variant 1-11285822-C-G is Pathogenic according to our data. Variant chr1-11285822-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 864.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr1-11285822-C-G is described in Lovd as [Pathogenic].
