Exome sequencing reveled a compound heterozygous mutations in RTTN gene causing developmental delay and primary microcephaly.

ABSTRACT: RTTN (Rotatin) (OMIM 614833) is a large centrosomal protein coding gene. RTTN mutations are responsible for syndromic forms of malformation of brain development, leading to polymicrogyria, microcephaly, primordial dwarfism, seizure along with many other malformations. In this study we have identified a compound heterozygous mutation in RTTN gene having NM_173630 c.5225A > G p.His1742Arg in exon 39 and NM_173630 c.6038G > T p.Cys2013Phe in exon 45 of a consanguineous Saudi family leading to brain malformation, seizure, developmental delay, dysmorphic feature and microcephaly. Whole exome sequencing (WES) techniques was used to identify the causative mutation in the affected members of the family. WES data analysis was done and obtained data were further confirmed by using Sang
