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]

Variant summary: EFEMP2 c.169G>A (p.Glu57Lys) results in a conservative amino acid change in the encoded protein sequence. 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. The variant was absent in 251214 control chromosomes. c.169G>A has been observed in individual(s) affected with Autosomal Recessive Cutis Laxa and related conditions (Hucthagowder_2006, Lascone_2012). These data indicate that the variant is likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. The results show that variant impacts protein function (Sasaki_2016). The following publications have been ascertained in the context of this evaluation (PMID: 16685658, 23212998, 27339457). ClinVar contains an entry for this variant (Variation ID: 5423). Based on the evidence outlined above, the variant was classified as pathogenic. -
