These CNVs were located in the gene bodies of CTDSPL, GALNTL6, and SNRPN. CTDSPL encodes a protein related to neuronal gene silencing in non-neuronal cells [43], GALNTL6 encodes a protein related to cell maturation and differentiation in the brain and testis [44], and SNRPN encodes a protein that plays a role in pre-mRNA processing and tissue-specific alternative splicing events (associated with Prader-Willi syndrome) [45]. Here, SNRPN is linked to Prader-Willi syndrome.
