Deficits in social communication, restricted interests, and repetitive behaviours are hallmarks of autism spectrum disorder (ASD). Despite high genetic heritability, the majority of clinically diagnosed ASD cases have unknown genetic origins. We performed genome sequencing on mothers, fathers, and affected individuals from 104 families with ASD in Oman, a Middle Eastern country underrepresented in international genetic studies.

This study describes two siblings from consanguineous parents who exhibit intellectual disability, microcephaly, photosensitivity, bilateral sensorineural hearing loss, numerous freckles, and other clinical features that suggest a potential disruption of the nucleotide excision repair (NER) pathway. Whole exome sequencing (WES) identified a novel homozygous missense variant in the gene, which was predicted to be pathogenic. However, a subsequent peculiar audiometric finding prompted further investigation, revealing a homozygous deletion in the gene linked to neurosensorial hearing loss.

: Neurodevelopmental disorders of genetic etiology are a highly diverse set of congenital recurrent complications triggered by irregularities in the basic tenets of brain development. : We present whole exome sequencing analysis and expression characteristics of the probands from four unrelated Pakistani consanguineous families with facial dysmorphism, neurodevelopmental, ophthalmic, auditory, verbal, psychiatric, behavioral, dental, and skeletal manifestations otherwise unexplained by clinical spectrum. : Whole exome sequencing identifies a novel, bi-allelic, missense variant in the gene [NM_152419.

: The gene encodes for the catalytic α subunit of Cytoplasmic phenylalanine-tRNA synthetase (FARS1), an essential enzyme for protein biosynthesis in transferring its amino acid component to tRNAs. Biallelic pathogenic variants have been associated with a multisystemic condition, characterized by variable expressivity and incomplete penetrance. Here, we report the case of an 11 year-old girl presenting interstitial lung disease, supratentorial leukoencephalopathy with brain cysts, hepatic dysfunction, hypoalbuminemia, skin and joint hyperlaxity, growth retardation, and dysmorphic features.

Stargardt disease (STGD1) is an autosomal recessive disorder caused by pathogenic variants in that affects the retina and is characterised by progressive central vision loss. The onset of disease manifestations varies from childhood to early adulthood. Whole exome (WES), whole gene, and whole genome sequencing (WGS) were performed for a patient with STGD1.
