Variants pathogenicity by type

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

• Disease: DISEASE: Sulfite oxidase deficiency, isolated (ISOD) [MIM:272300]: A life-threatening, autosomal recessive neurometabolic disorder characterized by severe neurological impairment. Classic ISOD manifests in the first few hours to days of life and is characterized by intractable seizures, feeding difficulties, rapidly progressive encephalopathy, microcephaly, and profound intellectual disability. Children usually die during the first few months of life. Mild ISOD manifests in infancy or early childhood and is characterized by ectopia lentis that is variably present, developmental delay and regression, movement disorder characterized by dystonia and choreoathetosis, ataxia, and rarely acute hemiplegia due to metabolic stroke. {ECO:0000269|PubMed:10519592, ECO:0000269|PubMed:12112661, ECO:0000269|PubMed:12368985, ECO:0000269|PubMed:9428520, ECO:0000269|PubMed:9600976}. Note=The disease is caused by mutations affecting the gene represented in this entry.
