Genes affected

ORMDL3 (HGNC:16038): (ORMDL sphingolipid biosynthesis regulator 3) Involved in ceramide metabolic process. Acts upstream of or within several processes, including negative regulation of B cell apoptotic process; negative regulation of ceramide biosynthetic process; and positive regulation of protein localization to nucleus. Located in endoplasmic reticulum. Part of SPOTS complex. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Mar 02, 2023

The c.122C>T (p.P41L) alteration is located in exon 2 (coding exon 1) of the ORMDL3 gene. This alteration results from a C to T substitution at nucleotide position 122, causing the proline (P) at amino acid position 41 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
