Novel ANKRD17 variants implicate synaptic and mitochondrial disruptions in intellectual disability and autism spectrum disorder.

ABSTRACT: ANKRD17 has recently been implicated in intellectual disability (ID) and autism spectrum disorder (ASD); however, the underlying molecular mechanisms remain unclear. Using trio whole-exome sequencing (Trio-WES) and chromosomal microarray analysis (CMA), we identified two unrelated cases with novel de novo heterozygous ANKRD17 variants. Case 1 describes a fetus with multiple congenital anomalies, where genetic analysis revealed a microdeletion at 4q13.3 truncating the ANKRD17 gene. Case 2 involves a 12-year-old male presenting with mild ID and progressive social impairments, associated with a NM_032217.5: c.1252 C > T (p.Arg418*) variation in ANKRD17. Our study highlighted in mouse models an association between Ankrd17 haploinsufficiency and deficits in social behavior, spatial learning and
