We present a male infant with hypertelorism, severe myopia and sensorineural deafness, diaphragmatic hernia, and proteinuria. This patient combines features of two distinct genetic conditions, the syndrome of diaphragmatic hernia, exomphalos, absent corpus callosum, hypertelorism, myopia, and sensorineural deafness (MIM 222448), and the facio-oculo-acoustico-renal syndrome (MIM 227290), which is characterised by similar anomalies, with the additional finding of proteinuria, but without diaphragmatic hernia. The present observations further suggest that these syndromes are the variable expression of a single autosomal recessive disorder.

Donnai-Barrow syndrome is associated with agenesis of the corpus callosum, congenital diaphragmatic hernia, facial dysmorphology, ocular anomalies, sensorineural hearing loss and developmental delay. By studying multiplex families, we mapped this disorder to chromosome 2q23.3-31.1 and identified LRP2 mutations in six families with Donnai-Barrow syndrome and one family with facio-oculo-acoustico-renal syndrome. LRP2 encodes megalin, a multiligand uptake receptor that regulates levels of diverse circulating compounds. This work implicates a pathway with potential pharmacological therapeutic targets.

The facio-oculo-acoustico-renal syndrome (FOAR) is a rare autosomal recessive syndrome characterized by the presence of dysmorphic facial features, ocular anomalies, sensorineural hearing loss, and proteinuria. Diaphragmatic hernia, exomphalos, absent or abnormal corpus callosum, and myopia, can also be part of the syndrome. The disorder is caused by mutations of the LRP2 gene located on chromosome 2q23.3-q31.1. We hereby report the case of a 56-year-old female patient with typical FOAR features. Molecular study of the LRP2 gene revealed the presence of a novel splice-site mutation. In addition to what was reported in FOAR syndrome, this patient had a megadolichocolon complicated by a volvulus and a late-onset renal failure which necessitated hemodyalisis and renal transplantation. Reporting aging patients with genetic syndromes will provide information about their special needs and lead to improvements in their follow-up.

Two siblings, from a consanguineous Iraqi family, were investigated to identify the underlying genetic cause of their high myopia, esotropia, vitreous changes and cataract. Subsequent investigation identified low molecular weight proteinuria as part of their syndrome. Exome sequencing of one of the probands revealed a new non-synonymous variant in the LRP2 gene. Sanger sequencing confirmed the mutation and segregation in the family. No mutation was identified in COL9A1/2, COL11A1/2, or COL2A1 genes. The variant (c.11483A>G; p.Asp3828Gly) is predicted to be damaging and is conserved among vertebrate species. Mutations in LRP2 have been shown to cause the Donnai-Barrow syndrome (DBS) or facio-oculo-acoustico-renal (FOAR) syndrome, a syndrome associated with facial dysmorphism, ocular anomalies, sensorineural hearing loss, low molecular weight proteinuria, and diaphragmatic hernia and absent corpus callosum, although there is variability in the expression of some features. This family shows a milder phenotype with a predominant eye phenotype similar to the Stickler syndrome and only a few features of the DBS, including microglobulinuria. The presence of microglobulinuria was only detected after molecular results were known. In conclusion, with the identification of a new mutation in LRP2 associated with a predominant eye phenotype similar to the Stickler syndrome, we have broadened the phenotypic spectrum of LRP2 mutations.
