Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the HERC2 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000004667.6. 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: E3 ubiquitin-protein ligase that regulates ubiquitin- dependent retention of repair proteins on damaged chromosomes. Recruited to sites of DNA damage in response to ionizing radiation (IR) and facilitates the assembly of UBE2N and RNF8 promoting DNA damage-induced formation of 'Lys-63'-linked ubiquitin chains. Acts as a mediator of binding specificity between UBE2N and RNF8. Involved in the maintenance of RNF168 levels. E3 ubiquitin-protein ligase that promotes the ubiquitination and proteasomal degradation of XPA which influences the circadian oscillation of DNA excision repair activity. By controlling the steady-state expression of the IGF1R receptor, indirectly regulates the insulin-like growth factor receptor signaling pathway (PubMed:26692333). {ECO:0000269|PubMed:20023648, ECO:0000269|PubMed:20304803, ECO:0000269|PubMed:22508508, ECO:0000269|PubMed:26692333}.
• Disease: DISEASE: Mental retardation, autosomal recessive 38 (MRT38) [MIM:615516]: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRT38 is characterized by global developmental delay affecting motor, speech, adaptive, and social development. Patients manifest autistic features, aggression, self-injury, impulsivity, and distractibility. {ECO:0000269|PubMed:23065719}. Note=The disease is caused by mutations affecting the gene represented in this entry.
