Genes affected
HEG1 (HGNC:29227): (heart development protein with EGF like domains 1) Predicted to enable calcium ion binding activity. Involved in several processes, including negative regulation of Rho protein signal transduction; negative regulation of Rho-dependent protein serine/threonine kinase activity; and negative regulation of membrane permeability. Located in cell-cell junction. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2024This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
