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 GeneticsJan 20, 2023The c.376A>C (p.K126Q) alteration is located in exon 4 (coding exon 4) of the ACER2 gene. This alteration results from a A to C substitution at nucleotide position 376, causing the lysine (K) at amino acid position 126 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
