Background Human genetically inherited cardiac diseases have been studied mainly in heterologous systems or animal models, independent of patients' genetic backgrounds. Because sources human cardiomyocytes ( CM s) are extremely limited, the use urine samples to generate induced pluripotent stem cell–derived s would be a noninvasive method identify dysfunctions that lead pathologies within specific The objective was validate CMs differentiated from urine‐derived (UhiPS) cells as new cellular...
Abstract Embryonic development is dictated by tight regulation of DNA replication, cell division and differentiation. Mutations in repair replication genes disrupt this equilibrium, giving rise to neurodevelopmental disease characterized microcephaly, short stature chromosomal breakage. Here, we identify biallelic variants two components the RAD18-SLF1/2-SMC5/6 genome stability pathway, SLF2 SMC5 , 11 patients with stature, cardiac abnormalities anemia. Patient-derived cells exhibit a unique...
A rare syndromic form of intellectual disability with impaired speech was recently found associated mutations in CHAMP1 (chromosome alignment-maintaining phosphoprotein 1), the protein product which is directly involved microtubule-kinetochore attachment. Through whole-exome sequencing six unrelated nonconsanguineous families having a sporadic case disability, we identified novel de novo truncating CHAMP1: c.1880C>G p.(Ser627*), c.1489C>T; p.(Arg497*), c.1876_1877delAG; p.(Ser626Leufs*4),...

We gathered international data from 17 new individuals 16 different (10 pathogenic and 6 uncertain significance), reviewed genotypic phenotypic 37 previously published families 34 variants.

Germline variants that disrupt components of the epigenetic machinery cause syndromic neurodevelopmental disorders. Using exome and genome sequencing, we identified de novo in KDM2A , a lysine demethylase crucial for embryonic development, 18 individuals with developmental delays and/or intellectual disabilities. The severity ranged from learning disabilities to severe disability. Other core symptoms included feeding difficulties, growth issues such as intrauterine restriction, short stature...
Abstract Background Genomics enables individualized diagnosis and treatment, but large challenges remain to functionally interpret rare variants. To date, only one causative variant has been described for KCNK9 imprinting syndrome (KIS). The genotypic phenotypic spectrum of KIS yet be the precise mechanism disease fully understood. Methods This study discovers mechanisms underlying (KIS) by describing 15 novel alterations from 47 KIS-affected individuals. We use clinical genetics...
ABSTRACT Individuals with monoallelic pathogenic variants in the histone lysine methyltransferase DOT1L display global developmental delay and varying congenital anomalies. However, impact of loss remains unclear. Here, we present a largely female cohort 11 individuals delays dysmorphic facial features. We found that include missense clustered catalytic domain, frameshift, stop-gain variants. demonstrate specific cause activity therefore sought to define effects decreased function. Using...
