Abstract
Neurodevelopmental syndromes due to copy number variation are well-known clinical entities. While the numerical variation of gene-harboring regions has been widely investigated at both molecular and clinical levels, much less is understood about unbalanced expression of long noncoding RNAs. Few studies have been performed on the clinical consequences of such unbalanced expression. Heterozygous deletions of NRXN1 have been well described to cause neuropsychological features. Heterozygous deletion of adjacent long noncoding RNA AK127244, either isolated or combined with partial NRXN1 deletion, was recently reported in association with neurodevelopmental delay. In our retrospective study, we analyze a bicentric cohort of 4 individuals, comprising 2 siblings, which bear an isolated heterozygous deletion in long noncoding RNA AK127244 and present with nonsyndromic neurodevelopmental delay.File | Size | Format | |
