Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the SARDH 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: Sarcosinemia (SARCOS) [MIM:268900]: A metabolic disorder characterized by an increased concentration of sarcosine in plasma and an increased excretion of sarcosine in urine. Sarcosinemia is most probably a benign condition without significant clinical problems. Some reports have associated sarcosinemia with mental retardation and neurologic problems. {ECO:0000269|PubMed:10444331, ECO:0000269|PubMed:22825317}. Note=The disease is caused by mutations affecting the gene represented in this entry.
