• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: -0.120

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_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.038554728).

Dec 14, 2023

The c.94C>T (p.P32S) alteration is located in exon 1 (coding exon 1) of the UBIAD1 gene. This alteration results from a C to T substitution at nucleotide position 94, causing the proline (P) at amino acid position 32 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
