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]

Computational evidence support a benign effect (BayesDel_noAF=-0.7).
BP6
Variant 11-65868384-G-A is Benign according to our data. Variant chr11-65868384-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 305380.
BP7
Synonymous conserved (PhyloP=-3.89 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000313 (457/1461642) while in subpopulation NFE AF = 0.000399 (444/1112006). AF 95% confidence interval is 0.000368. There are 0 homozygotes in GnomAdExome4. There are 218 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
