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]

SRFBP1 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Jul 14, 2017	Variant summary: The LOX c.476C>A (p.Pro159Gln) variant involves the alteration of a non-conserved nucleotide. 2/3 in silico tools predict a damaging outcome for this variant (SNPsandGO not captured due to low reliability index), however in silico prediction results are not definitive. This variant was found in 659/118824 control chromosomes (4 homozygotes) from ExAC at a frequency of 0.005546, which is approximately 333 times the estimated maximal expected allele frequency of a pathogenic LOX variant (0.0000167), suggesting this variant is likely a benign polymorphism. It has been reported as a polymorphism in literature (De Bonis_2011). Taken together, this variant is classified as benign. -

This alteration is classified as likely 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. -
