Interstitial deletion of chromosome region 3p14.1, including FOXP1 gene, is relatively rare and, until recently, there were no strong evidences to support the hypothesis that this microdeletion could play a role in the etiology of genomic disorders. Here, we report on an adult patient with a recognizable phenotype of autism, severe speech delay, deficit of(More)
CHARGE syndrome is an autosomal dominant inherited disorder characterized by a specific and recognizable pattern of anomalies. De novo mutations or deletions of the gene encoding chromodomain helicase DNA binding protein 7 (CHD7) are the major cause of CHARGE syndrome. In this report, we describe a patient with a typical phenotype characterized by(More)
Duplications in the ~2 Mb desert region upstream of SOX9 at 17q24.3 may result in familial 46,XX disorders of sex development (DSD) without any effects on the XY background. A balanced translocation with its breakpoint falling within the same region has also been described in one XX DSD subject. We analyzed, by conventional and molecular cytogenetics, 19(More)
6q16 deletions have been described in patients with a Prader–Willi-like (PWS-like) phenotype. Recent studies have shown that certain rare single-minded 1 (SIM1) loss-of-function variants were associated with a high intra-familial risk for obesity with or without features of PWS-like syndrome. Although SIM1 seems to have a key role in the phenotype of(More)
We provide a detailed clinical and molecular characterization of an 11-year-old female patient presenting with neurodevelopmental delay (NDD), intellectual disability (ID), seizures, stereotypies and dysmorphic features. Chromosomal microarrays analysis (CMA) detected a small, rare de novo deletion on chromosome 12q24.31 encompassing 31 protein-coding(More)
Wolfram Syndrome type 2 (WFS2) is considered a phenotypic and genotypic variant of WFS, whose minimal criteria for diagnosis are diabetes mellitus and optic atrophy. The disease gene for WFS2 is CISD2. The clinical phenotype of WFS2 differs from WFS1 for the absence of diabetes insipidus and psychiatric disorders, and for the presence of bleeding upper(More)
Purpose:The harmful effects of inbreeding are well known by geneticists, and several studies have already reported cases of intellectual disability caused by recessive variants in consanguineous families. Nevertheless, the effects of inbreeding on the degree of intellectual disability are still poorly investigated. Here, we present a detailed analysis of(More)
Pure interstitial duplications of chromosome band 4p16.3 represent an infrequent chromosomal finding with, to the best of our knowledge, only two patients to date reported. We report on a 13-year-old boy showing a set of dysmorphic facial features, attention deficit hyperactivity disorders, learning difficulties, speech and cognitive delays, overgrowth and(More)
The human chromosome 14q32 carries a cluster of imprinted genes which include the paternally expressed genes (PEGs) DLK1 and RTL1, as well as the maternally expressed genes (MEGs) MEG3, RTL1as, and MEG8. PEGs and MEGs expression at the 14q32.2-imprinted region are regulated by two differentially methylated regions (DMRs): the IG-DMR and the MEG3-DMR, which(More)
