  • Title: Novel variants identified in CKAP2L in two siblings with Filippi syndrome.
    Author: Patrick RJ, Weimer J, Davis-Keppen L, Landsverk ML.
    Journal: Cold Spring Harb Mol Case Stud; 2022 Feb; 8(2):. PubMed ID: 34921061.
    Abstract:
    Pathogenic variants in CKAP2L have previously been reported in Filippi syndrome (FS), a rare autosomal recessive, craniodigital syndrome characterized by microcephaly, syndactyly, short stature, intellectual disability, and dysmorphic facial features. To date, fewer than 10 patients with pathogenic variants in CKAP2L associated with FS have been reported. All of the previously reported probands have presumed loss-of-function variants (frameshift, canonical splice site, starting methionine), and all but one have been homozygous for a pathogenic variant. Here we describe two brothers who presented with microcephaly, micrognathia, syndactyly, dysmorphic features, and intellectual disability. Whole-exome sequencing of the family identified a missense variant, c.2066G > A;p.(Arg689His), in trans with a frameshift variant, c.1169_1173del;p.(Ile390LysfsTer4), in CKAP2L To our knowledge, these are the first patients with FS to be reported with a missense variant in CKAP2L and only the second family to be reported with two variants in trans.
