Genes affected

TACSTD2 (HGNC:11530): (tumor associated calcium signal transducer 2) This intronless gene encodes a carcinoma-associated antigen. This antigen is a cell surface receptor that transduces calcium signals. Mutations of this gene have been associated with gelatinous drop-like corneal dystrophy.[provided by RefSeq, Dec 2009]

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, 0.988
• PP5: Variant 1-58576802-A-T is Pathogenic according to our data. Variant chr1-58576802-A-T is described in ClinVar as [Pathogenic]. Clinvar id is 16187.Status of the report is no_assertion_criteria_provided, 0 stars.
