Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TBX18 gene is commonly pathogenic or not. These statistics are base on transcript: NM_001080508.3. Only rare variants are included in the table.

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: Acts as transcriptional repressor involved in developmental processes of a variety of tissues and organs, including the heart and coronary vessels, the ureter and the vertebral column. Required for embryonic development of the sino atrial node (SAN) head area. {ECO:0000250|UniProtKB:Q9EPZ6, ECO:0000269|PubMed:26235987}.;
Disease: DISEASE: Congenital anomalies of kidney and urinary tract 2 (CAKUT2) [MIM:143400]: A disorder encompassing a broad spectrum of renal and urinary tract malformations that include renal agenesis, kidney hypodysplasia, multicystic kidney dysplasia, duplex collecting system, posterior urethral valves and ureter abnormalities. Congenital anomalies of kidney and urinary tract are the commonest cause of chronic kidney disease in children. {ECO:0000269|PubMed:26235987}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
