(2022-01-04)INNGANGUR Formleg erfðaráðgjafareining hefur verið starfrækt á Landspítala við Hringbraut frá árinu 2006. Samhliða hefur áhugi og þörf á erfðalæknisfræði í almennri heilbrigðisþjónustu aukist til muna. Í þessari grein er starfsemi og útkoma erfðarannsókna ... -
(2021-07)Purpose: The variant spectrum and the phenotype of X-linked Kabuki syndrome type 2 (KS2) are poorly understood. Methods: Genetic and clinical details of new and published individuals with pathogenic KDM6A variants were compiled and analyzed. Results: ...
-
(2022-06-16)Background: Cardiomyopathy is a known complication of organic acidemias but generally thought to be secondary to poor metabolic control. Methods: Our patient was found through biochemical testing and Sanger sequencing to harbor an Icelandic founder ...
-
(2023-03-23)The multidisciplinary Epigenetics and Chromatin Clinic at Johns Hopkins provides comprehensive medical care for individuals with rare disorders that involve disrupted epigenetics. Initially centered on classical imprinting disorders, the focus shifted ...
-
(2023-06)OBJECTIVES: Wiedemann-Steiner syndrome (WSS) is a rare Mendelian disorder of the epigenetic machinery caused by heterozygous pathogenic variants in KMT2A. Currently, the specific neurocognitive profile of this syndrome remains unknown. This case series ...
-
(2021-03-12)Kabuki syndrome (KS) is a rare cause of intellectual disability primarily caused by loss-of-function mutations in lysine-specific methyltransferase 2D ( KMT2D), which normally adds methyl marks to lysine 4 on histone 3. Previous studies have shown that ...
-
(2024-01)Individuals with Kabuki syndrome type 1 (KS1) often have hearing loss recognized in middle childhood. Current clinical dogma suggests that this phenotype is caused by frequent infections due to the immune deficiency in KS1 and/or secondary to structural ...
-
(2022-06-21)Wiedemann-Steiner syndrome (WDSTS) is a neurodevelopmental disorder caused by de novo variants in KMT2A, which encodes a multi-domain histone methyltransferase. To gain insight into the currently unknown pathogenesis of WDSTS, we examined the spatial ...
-
(2024-01-09)Weaver syndrome is a Mendelian disorder of the epigenetic machinery (MDEM) caused by germline pathogenic variants in EZH2, which encodes the predominant H3K27 methyltransferase and key enzymatic component of Polycomb repressive complex 2 (PRC2). Weaver ...
-
(2022-10-06)Kabuki syndrome (KS) is a Mendelian Disorder of the Epigenetic Machinery (MDEM) caused by loss of function variants in either of two genes involved in the regulation of histone methylation, KMT2D (34–76%) or KDM6A (9–13%). Previously, representative ...
-
(2023-12)Background: Recent findings from studies of mouse models of Mendelian disorders of epigenetic machinery strongly support the potential for postnatal therapies to improve neurobehavioral and cognitive deficits. As several of these therapies move into ...
-
(2023)Marfan syndrome (MFS) is an autosomal dominant condition characterized by aortic aneurysm, skeletal abnormalities, and lens dislocation, and is caused by variants in the FBN1 gene. To explore causes of MFS and the prevalence of the disease in Iceland ...
-
(2022-01)Introduction: Kabuki syndrome is a rare congenital condition characterized clinically by unique facial features, abnormalities in the skeleton, finger pad abnormalities, and developmental delays, as well as a range of other health issues. Existing ...
-
(2021-08-31)Malignant hyperthermia (MH) susceptibility is a rare life-threatening disorder that occurs upon exposure to a triggering agent. MH is commonly due to protein-altering variants in RYR1 and CACNA1S. The American College of Medical Genetics and Genomics ...
-
(2022-10-13)Wiedemann-Steiner syndrome (WSS) is a rare genetic disorder caused by mutation in KMT2A and characterized by neurodevelopmental delay. This study is the first prospective investigation to examine the sleep and behavioral phenotypes among those with WSS ...
-
(2023-02)BACKGROUND: Wiedemann-Steiner syndrome (WSS) is a rare genetic disorder caused by heterozygous variants in KMT2A. To date, the cognitive profile associated with WSS remains largely unknown, although emergent case series implicate increased risk of ...
-
(2022-01-31)Background: The cell cycle is a highly conserved, continuous process which controls faithful replication and division of cells. Single-cell technologies have enabled increasingly precise measurements of the cell cycle both as a biological process of ...
-
(2023-01)Several mitochondrial diseases are caused by pathogenic variants that impair membrane phospholipid remodeling, with no FDA-approved therapies. Elamipretide targets the inner mitochondrial membrane where it binds to cardiolipin, resulting in improved ...
