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.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.10G>A (p.A4T) alteration is located in exon 1 (coding exon 1) of the ACER3 gene. This alteration results from a G to A substitution at nucleotide position 10, causing the alanine (A) at amino acid position 4 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 4 of the ACER3 protein (p.Ala4Thr). This variant is present in population databases (rs746227737, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with ACER3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1478169). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
