Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the MID1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000000381.4. 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: Has E3 ubiquitin ligase activity towards IGBP1, promoting its monoubiquitination, which results in deprotection of the catalytic subunit of protein phosphatase PP2A, and its subsequent degradation by polyubiquitination. {ECO:0000269|PubMed:10400985, ECO:0000269|PubMed:11685209, ECO:0000269|PubMed:22613722}.
• Disease: DISEASE: Opitz GBBB syndrome 1 (GBBB1) [MIM:300000]: A congenital midline malformation syndrome characterized by hypertelorism, genital-urinary defects such as hypospadias in males and splayed labia in females, cleft lip/palate, laryngotracheoesophageal abnormalities, imperforate anus, developmental delay and congenital heart defects. {ECO:0000269|PubMed:11030761, ECO:0000269|PubMed:15558842, ECO:0000269|PubMed:9354791, ECO:0000269|PubMed:9718340}. Note=The disease is caused by mutations affecting the gene represented in this entry. MID1 mutations produce proteins with a decreased affinity for microtubules.
