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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PP3
Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
BP6
Variant 11-65868041-C-T is Benign according to our data. Variant chr11-65868041-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 472834.We mark this variant Likely_benign, oryginal submissions are: {Benign=2, Uncertain_significance=2}.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000926 (141/152208) while in subpopulation AFR AF= 0.00289 (120/41540). AF 95% confidence interval is 0.00247. There are 1 homozygotes in gnomad4. There are 68 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
