We have identified TUBGCP4 variants in individuals with autosomal-recessive
microcephaly and chorioretinopathy. Whole-exome sequencing performed on one
family with two affected siblings and independently on another family with one
affected child revealed compound-heterozygous mutations in TUBGCP4. Subsequent
Sanger sequencing was performed on a panel of individuals from 12 French families
affected by microcephaly and ophthalmic manifestations, and one other individual
was identified with compound-heterozygous mutations in TUBGCP4. One synonymous
variant was common to all three families and was shown to induce exon skipping;
the other mutations were frameshift mutations and a deletion. TUBGCP4 encodes
?-tubulin complex protein 4, a component belonging to the ?-tubulin ring complex
(?-TuRC) and known to regulate the nucleation and organization of microtubules.
Functional analysis of individual fibroblasts disclosed reduced levels of the
?-TuRC, altered nucleation and organization of microtubules, abnormal nuclear
shape, and aneuploidy. Moreover, zebrafish treated with morpholinos against
tubgcp4 were found to have reduced head volume and eye developmental anomalies
with chorioretinal dysplasia. In summary, the identification of TUBGCP4 mutations
in individuals with microcephaly and a spectrum of anomalies in eye development,
particularly photoreceptor anomalies, provides evidence of an important role for
the ?-TuRC in brain and eye development.
