Genes affected

EFEMP2 (HGNC:3219): (EGF containing fibulin extracellular matrix protein 2) A large number of extracellular matrix proteins have been found to contain variations of the epidermal growth factor (EGF) domain and have been implicated in functions as diverse as blood coagulation, activation of complement and determination of cell fate during development. The protein encoded by this gene contains four EGF2 domains and six calcium-binding EGF2 domains. This gene is necessary for elastic fiber formation and connective tissue development. Defects in this gene are cause of an autosomal recessive cutis laxa syndrome. Alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, Jan 2011]

This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 412 of the EFEMP2 protein (p.Val412Leu). This variant is present in population databases (rs146879673, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with EFEMP2-related conditions. ClinVar contains an entry for this variant (Variation ID: 581197). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
