Genes affected

LOX (HGNC:6664): (lysyl oxidase) This gene encodes a member of the lysyl oxidase family of proteins. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate a regulatory propeptide and the mature enzyme. The copper-dependent amine oxidase activity of this enzyme functions in the crosslinking of collagens and elastin, while the propeptide may play a role in tumor suppression. In addition, defects in this gene have been linked with predisposition to thoracic aortic aneurysms and dissections. [provided by RefSeq, Jul 2016]

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Jul 17, 2017	Variant summary: The LOX c.225C>G (p.Ala75Ala) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. Mutation taster predicts a damaging outcome for this variant. 4/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may affect binding of multiple ESE sites. However, these predictions have yet to be confirmed by functional studies. This variant was found in 234/21640 control chromosomes (7 homozygotes) from ExAC at a frequency of 0.0108133, which is approximately 649 times the estimated maximal expected allele frequency of a pathogenic LOX variant (0.0000167), strongly indicating this variant is likely a benign polymorphism. Taken together, this variant is classified as benign. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
