Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PCK1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000002591.4. 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: Catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP), the rate-limiting step in the metabolic pathway that produces glucose from lactate and other precursors derived from the citric acid cycle. {ECO:0000269|PubMed:24863970, ECO:0000269|PubMed:26971250, ECO:0000269|PubMed:28216384}.;
Disease
DISEASE: Phosphoenolpyruvate carboxykinase deficiency, cytosolic (PCKDC) [MIM:261680]: An autosomal recessive metabolic disorder characterized by impaired gluconeogenesis, hypoglycemia, hypotonia, hepatomegaly, hepatic dysfunction, failure to thrive, lactic acidosis, and elevated tricarboxylic acid intermediates, particularly fumarate, in urine. {ECO:0000269|PubMed:24863970, ECO:0000269|PubMed:26971250, ECO:0000269|PubMed:28216384}.
