Abstract
BACKGROUND A multitude of studies have highlighted that copy number variants (CNVs) are associated with neurodevelopmental disorders (NDDs) characterized by a wide range of clinical characteristics. Benefiting from CNV calling from WES data, WES has emerged as a more powerful and cost-effective molecular diagnostic tool, which has been widely used for the diagnosis of genetic diseases, especially NDDs. To our knowledge, isolated deletions on chromosome 1p13.2 are rare. To date, only a few patients were reported with 1p13.2 deletions and most of them were sporadic. Besides, the correlation between 1p13.2 deletions and NDDs remained unclear. CASE PRESENTATION Here, we first reported five members in a three-generation Chinese family who presented with NDDs and carried a novel 1.41 Mb heterozygous 1p13.2 deletion with precise breakpoints. The diagnostic deletion contained 12 protein-coding genes and was observed to segregate with NDDs among the members of our reported family. Whether those genes contribute to the patient's phenotypes is still inconclusive. CONCLUSIONS We hypothesized that the NDD phenotype of our patients was caused by the diagnostic 1p13.2 deletion. However, further in-depth functional experiments are still needed to establish a 1p13.2 deletion-NDDs relationship. Our study might supplement the spectrum of 1p13.2 deletion-NDDs.

Abstract
BACKGROUNDSquamosal sutures are minor sutures of the human skull. Early isolated fusion of the sutures (squamosal synostosis) is rarely found.OBSERVATIONSThe authors report a case of a girl who presented with an abnormal head shape and bilateral squamosal synostosis. Genetic testing revealed a chromosome 1p12–1p13.3 deletion. She has been managed with conservative treatment of the synostosis. She has global developmental delay and multiple anomalies due to the chromosome abnormality.LESSONSIsolated squamosal suture synostosis could be an uncommon feature of chromosome 1p12–1p13.3 deletion.

Abstract
Deregulated RAS signaling is associated with increasing numbers of congenital diseases usually referred to as RASopathies. The spectrum of genes and mutant alleles causing these diseases has been significantly expanded in recent years. This progress has triggered new challenges, including the origin and subsequent selection of the mutations driving these diseases, the specific pathobiological programs triggered by those mutations, the type of correlations that exist between the genotype and the clinical features of patients, and the ancillary genetic factors that influence the severity of the disease in patients. These issues also directly impinge on the feasibility of using RAS pathway drugs to treat RASopathy patients. Here, we will review the main developments and pending challenges in this research topic.
