Genes affected

NAAA (HGNC:736): (N-acylethanolamine acid amidase) Enables N-(long-chain-acyl)ethanolamine deacylase activity; N-acylsphingosine amidohydrolase activity; and fatty acid amide hydrolase activity. Involved in several processes, including N-acylethanolamine metabolic process; N-acylphosphatidylethanolamine metabolic process; and sphingosine metabolic process. Located in lysosome. Is extrinsic component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Mar 24, 2023

The c.803C>T (p.P268L) alteration is located in exon 6 (coding exon 6) of the NAAA gene. This alteration results from a C to T substitution at nucleotide position 803, causing the proline (P) at amino acid position 268 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
