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:26333): (serum response factor binding protein 1) Enables RNA binding activity. Predicted to be involved in maturation of SSU-rRNA. Predicted to be located in perinuclear region of cytoplasm. Predicted to be part of 90S preribosome. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.806

The p.G411V variant (also known as c.1232G>T), located in coding exon 6 of the LOX gene, results from a G to T substitution at nucleotide position 1232. The glycine at codon 411 is replaced by valine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
