ClinVar
This is a list of variants' phenotypes submitted to
Variants pathogenicity by type
Statistics on ClinVar variants can assist in determining whether a specific variant type in the GJC1 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.
