Condition	Inheritance	Intervention Categories	Intervention/Rationale	Manifestation Categories	References
Lower urinary tract obstruction, congenital	AD	Renal	The condition may involve occult urinary tract obstruction, which may manifest as frequent urinary tract infections and other sequelae, leading to renal damage, and awareness may allow interventions to preserve kidney function	Renal	31051115

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the BNC2 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.
