Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PRSS56 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Serine protease required during eye development. {ECO:0000269|PubMed:21397065}.
• Disease: DISEASE: Microphthalmia, isolated, 6 (MCOP6) [MIM:613517]: A developmental ocular disorder characterized by small malformed eyes. Clinical features are extreme hyperopia due to short axial length with essentially normal anterior segment, steep corneal curvatures, shallow anterior chamber, thick lenses, and thickened scleral wall. Palpebral fissures appear narrow because of relatively deep-set eyes, visual acuity is mildly to moderately reduced, and anisometropic or strabismic amblyopia is common. The fundus of the eye shows crowded optical disks, tortuous vessels, and an abnormal foveal avascular zone. {ECO:0000269|PubMed:21397065, ECO:0000269|PubMed:21532570, ECO:0000269|PubMed:21850159}. Note=The disease is caused by mutations affecting the gene represented in this entry.
