    Description

    The copy number gain of Xp11.4p11.22 involves numerous protein-coding genes, including SHROOM4 (OMIM 300579), FTSJ1 (OMIM 300499), DGKK (OMIM 300837), BMP15 (OMIM 300247), PQBP1 (OMIM 300463), and SLC35A2 (OMIM 314375), and is expected to cause phenotypic and/or developmental abnormalities. This region overlaps a recurrent copy number gain associated with X-linked dominant chromosome Xp11.23-p11.22 duplication syndrome (OMIM 300801). Both males and females with this copy number gain are affected. Common clinical features include mild facial dysmorphism, mild to severe intellectual disability, language impairment, early onset of puberty, and epilepsy. Foot abnormalities, 5th finger clinodactyly, tapering fingers, constipation, and exercise intolerance are also observed (Grams 2016). Several candidate genes have been proposed for these phenotypes: SHROOM4, FTSJ1, and DGKK for intellectual disability, BMP15 for early onset of puberty, and PQBP1 and SLC35A2 for epilepsy (Grams 2016, Nizon 2015). Furthermore, there are no similar copy number gains of this region in the general populations of the Database of Genomic Variants. Thus, the clinical significance of this copy number variant (CNV) is pathogenic. References: Grams et al., Am J Med Genet A. 2016 Apr;170A(4):967-77. PMID: 26692240.
