Genes affected
ACER2 (HGNC:23675): (alkaline ceramidase 2) The sphingolipid metabolite sphingosine-1-phosphate promotes cell proliferation and survival, whereas its precursor, sphingosine, has the opposite effect. The ceramidase ACER2 hydrolyzes very long chain ceramides to generate sphingosine (Xu et al., 2006 [PubMed 16940153]).[supplied by OMIM, Jul 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2023The c.391G>A (p.V131I) alteration is located in exon 4 (coding exon 4) of the ACER2 gene. This alteration results from a G to A substitution at nucleotide position 391, causing the valine (V) at amino acid position 131 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
