چکیده
HERC۲-associated neurodevelopmental disorders (NDD) refer to a group of medical conditionsresulting from genetic mutations in the HERC۲ gene. These disorders can present a range of symptomsaffecting the brain and nervous system, such as delayed psychomotor development, severe mentalretardation, seizures, and autistic features. Whole exome sequencing (WES) was conducted on a tenyear-old male patient who was referred to the genetic center for genetic evaluation. To gain a deeperinsight into the effects of the mutation, a comprehensive analysis was carried out utilizingbioinformatics tools. The analysis of WES data revealed a homozygous single nucleotide alteration(C> T) at position c.۱۴۲۱۵ within exon ninety-two of the HERC۲ gene. This study demonstrated that thesubstitution of arginine with a stop codon in the Hect domain resulted in a premature stop codon atposition ۴۷۳۹. This mutation substantially disrupts the exonic splicing enhancer (ESE) element in exonninety-two, potentially leading to exon skipping.The discovery of a novel pathogenic variant situatedwithin exon ninety-two of the HERC۲ gene is significant due to its association with an autosomalrecessive inheritance pattern in cases of intellectual developmental disorder (IDD). Ultimately, thisvariant may contribute to the underlying mechanisms that lead to the onset of intellectual developmentaldisorder.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
