- Abstract
We report a four-generation pedigree with six affected females with cranial hyperostosis and various skeletal abnormalities. The phenotype is similar to frontometaphyseal dysplasia, which is part of the otopalatodigital (OPD) spectrum. We identified a novel in-frame deletion in exon 29 of the Filamin A gene (c.4904_4912del, p.R1635_V1637del) encoding rod domain repeat 14 of the protein. The disorder resulted in early lethality in male children. The phenotype of female individuals in this family is variable and rather mild, and bridges the phenotypes of various OPD-spectrum disorders.
