Variant summary: EVC2 c.3870_3893dup24 (p.Lys1293_Lys1300dup) results in an in-frame duplication that is predicted to duplicate 8 amino acids into the encoded protein. The variant was absent in 251424 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.3870_3893dup24 has been reported in the literature in at least one homozygous individual affected with Meckel-Gruber syndrome (Shaheen_2013). These report(s) do not provide unequivocal conclusions about association of the variant with Ellis-van Creveld syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 29620724, 23169490, 34645488). ClinVar contains an entry for this variant (Variation ID: 183329). Based on the evidence outlined above, the variant was classified as uncertain significance. -
