Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the NEK8 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000178170.3. 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: Required for renal tubular integrity. May regulate local cytoskeletal structure in kidney tubule epithelial cells. May regulate ciliary biogenesis through targeting of proteins to the cilia (By similarity). Plays a role in organogenesis and is involved in the regulation of the Hippo signaling pathway. {ECO:0000250, ECO:0000269|PubMed:23418306}.
• Disease: DISEASE: Renal-hepatic-pancreatic dysplasia 2 (RHPD2) [MIM:615415]: A form of renal-hepatic-pancreatic dysplasia, a disease characterized by cystic malformations of the kidneys, liver, and pancreas. The pathological findings consist of multicystic dysplastic kidneys, dilated and dysgenetic bile ducts, a dysplastic pancreas with dilated ducts, cysts, fibrosis and inflammatory infiltrates. {ECO:0000269|PubMed:23418306}. Note=The disease is caused by mutations affecting the gene represented in this entry.
