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.

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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with ACER3-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 53 of the ACER3 protein (p.Gln53Arg). -
