Genes affected

ACER3 (HGNC:16066): (alkaline ceramidase 3) Enables N-acylsphingosine amidohydrolase activity and metal ion binding activity. Involved in several processes, including myelination; positive regulation of cell population proliferation; and sphingolipid metabolic process. Is integral component of Golgi membrane and integral component of endoplasmic reticulum membrane. Biomarker of hepatocellular carcinoma and non-alcoholic steatohepatitis.

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 50 of the ACER3 protein (p.Gly50Ser). This variant is present in population databases (rs372314534, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with ACER3-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ACER3 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
