Genes affected
PCK1 (HGNC:8724): (phosphoenolpyruvate carboxykinase 1) This gene is a main control point for the regulation of gluconeogenesis. The cytosolic enzyme encoded by this gene, along with GTP, catalyzes the formation of phosphoenolpyruvate from oxaloacetate, with the release of carbon dioxide and GDP. The expression of this gene can be regulated by insulin, glucocorticoids, glucagon, cAMP, and diet. Defects in this gene are a cause of cytosolic phosphoenolpyruvate carboxykinase deficiency. A mitochondrial isozyme of the encoded protein also has been characterized. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

PP3
Multiple lines of computational evidence support a deleterious effect 10: AlphaMissense, Cadd, Dann, Eigen, FATHMM_MKL, MutationAssessor, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when BayesDel_addAF, max_spliceai, MetaRNN, MutationTaster was below the threshold]
PP5
Variant 20-57563691-G-A is Pathogenic according to our data. Variant chr20-57563691-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 338886.
BP4
Computational evidence support a benign effect (MetaRNN=0.062205642). . Strength limited to SUPPORTING due to the PP5.
BS2
High Homozygotes in GnomAdExome4 at 3 AR gene
