Nanopore Sequencing in adults with autism spectrum disorder (ASD) without intellectual disability

This pilot study investigates the genetic and epigenetic underpinnings of late-diagnosed autism spectrum disorder (ASD) without intellectual disability or language impairment using long-read nanopore whole-genome sequencing. This approach allows the simultaneous analysis of complex structural variants (SVs) and DNA methylation patterns in genomic regions often missed by short-read methods, such as intronic, non-coding and repetitive regions.

EGAD50000002495	Nanopore whole-genome sequencing was performed on DNA from peripheral blood samples of 10 individuals with ASD and 10 sex- and age-matched non-autistic controls (NC). DNA preparation and sequencing was performed according to the Oxford Nanopore Technologies (ONT; Oxford, UK) manual “Ligation Sequencing gDNA V14 - human sample (N50 30 kb) on PromethION (SQK-LSK114)” (version GDH_9174_v114_revF_10Nov2022) using ONT R10.4.1 PromethION flow cells. Sequencing was performed on an ONT PromethION 2 Solo using ONT MinKNOW software. Base and modification calling as well as alignment was performed with the ONT dorado basecalling software v0.5.3 using the model dna_r10.4.1_e8.2_400bps_hac@v4.2.0 and flag --modified-bases 5mCG_5hmCG with GenBank GCA_0000001405.15 (GRCh38) as reference sequence. This dataset contains the resulting modBAMs (.bam file format) sorted and indexed using samtools (Danecek et al., 2021) with indexes in bam.bai file format.	PromethION	20
