Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the GATAD2B 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: Transcriptional repressor. Enhances MBD2-mediated repression. Efficient repression requires the presence of GATAD2A. Targets MBD3 to discrete loci in the nucleus. May play a role in synapse development. {ECO:0000269|PubMed:12183469, ECO:0000269|PubMed:16415179}.
• Disease: DISEASE: Mental retardation, autosomal dominant 18 (MRD18) [MIM:615074]: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRD18 patients have severe intellectual disability and dysmorphic features. {ECO:0000269|PubMed:23033978, ECO:0000269|PubMed:23644463}. Note=The disease is caused by mutations affecting the gene represented in this entry.
