Genes affected

AOAH (HGNC:548): (acyloxyacyl hydrolase) This locus encodes both the light and heavy subunits of acyloxyacyl hydrolase. The encoded enzyme catalyzes the hydrolysis of acyloxylacyl-linked fatty acyl chains from bacterial lipopolysaccharides, effectively detoxifying these molecules. The encoded protein may play a role in modulating host inflammatory response to gram-negative bacteria. Alternatively spliced transcript variants have been described.[provided by RefSeq, Apr 2010]

The c.1639G>T (p.V547L) alteration is located in exon 21 (coding exon 21) of the AOAH gene. This alteration results from a G to T substitution at nucleotide position 1639, causing the valine (V) at amino acid position 547 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
