We report on a child with Filippi syndrome who shows syndactyly of fingers and toes, severe pre- and post-natal growth retardation, postnatal microcephaly, epilepsy, and severe mental retardation with speech impairment. Standard cytogenetics, CGH microarray, and molecular analysis of the GJA1 (Cx43) gene coding region were normal. We review the literature and provide additional information delineating the genetic and neurological aspects of the syndrome.

Filippi syndrome is a rare genetic disorder characterized by growth and neurodevelopmental delays, dysmorphism, and selective limb abnormalities. Although the syndrome was described approximately four decades ago, only a few families with molecularly confirmed diagnoses have been reported. In this article, we present three new patients of Filippi syndrome with unusual clinical and genetic aspects.

Pathogenic variants in 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 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.

Filippi syndrome (MIM #272440), one of the craniodigital syndromes, is a rare genetic entity with autosomal recessive inheritance and characterized by pre- and postnatal growth retardation, microcephaly, distinctive facial appearance, developmental delay/intellectual disability, and variable syndactylies of the fingers and toes. In this report, a further female patient of Filippi syndrome who additionally had a unilateral congenital talipes equinovarus (CTEV), a feature not previously recorded, is described. Genetic testing revealed a novel homozygous frameshift pathogenic variant (c.
