Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the DDRGK1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000023935.3. 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: Protein which interacts with the E3 UFM1-protein ligase UFL1 and one of its substrates TRIP4 and is required for TRIP4 ufmylation. Through TRIP4 ufmylation may regulate nuclear receptors-mediated transcription (PubMed:25219498). May play a role in NF-kappa-B-mediated transcription through regulation of the phosphorylation and the degradation of NFKBIA, the inhibitor of NF-kappa-B (PubMed:23675531). May also play a role in the cellular response to endoplasmic reticulum stress (By similarity). Plays a role in cartilage development through SOX9, inhibiting the ubiquitin-mediated proteasomal degradation of this transcriptional regulator (PubMed:28263186). {ECO:0000250|UniProtKB:Q80WW9, ECO:0000269|PubMed:23675531, ECO:0000269|PubMed:25219498, ECO:0000269|PubMed:28263186}.;
Disease: DISEASE: Spondyloepimetaphyseal dysplasia, Shohat type (SEMDSH) [MIM:602557]: An autosomal recessive skeletal dysplasia that affects cartilage development. It is characterized by vertebral, epiphyseal, and metaphyseal abnormalities, including scoliosis with vertebral compression fractures, flattened vertebral bodies, and hypomineralization of long bones. Affected individuals may exhibit a small trunk, short neck, small limbs, joint laxity, bowlegs, and/or abdominal distension with hepatosplenomegaly. {ECO:0000269|PubMed:28263186}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
