Postnatal microcephaly and retinal involvement expand the phenotype of RPL10-related disorder.

ABSTRACT: Hemizygous missense variants in the RPL10 gene encoding a ribosomal unit are responsible for an X-linked syndrome presenting with intellectual disability (ID), autism spectrum disorder, epilepsy, dysmorphic features, and multiple congenital anomalies. Among 15 individuals with RPL10-related disorder reported so far, only one patient had retinitis pigmentosa and microcephaly was observed in approximately half of the cases. By exome sequencing, three Italian and one Spanish male children, from three independent families, were found to carry the same hemizygous novel missense variant p.(Arg32Leu) in RPL10, inherited by their unaffected mother in all cases. The variant, not reported in gnomAD, is located in the 28S rRNA binding region, affecting an evolutionary conserved residue and predicted
