Phenotypic Characterization of Seven Pediatric Patients Diagnosed With KAT6B‐Related Disorders: Case Series and Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Genitopatellar syndrome (GPS) and Say‐Barber‐Biesecker‐Young‐Simpson Syndrome (SBBYSS) are clinically distinct neurodevelopmental disorders caused by monoallelic pathogenic variants in KAT6B. In some cases, GPS and SBBYSS features can overlap, determining an intermediate phenotype.

Worth the Effort: Lessons for Discovery and Care From an Unusual Case of Gorlin Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gorlin‐Goltz Syndrome (GGS) is a rare autosomal dominant genetic disorder encompassing a diverse range of clinical manifestations, including congenital anomalies and predisposition to cancer. Pathogenic variants in PTCH1 and SUFU account for up to 79% and 6% of cases, respectively. Currently, an estimated 15%–27% of individuals with a clinical

Truncating Variants in RREB1 Cause a Novel RASopathy Syndrome of Congenital Heart Disease, Genitourinary Malformations, and Developmental Delay

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The interstitial 6p microdeletion syndrome is characterized by dysmorphic facies and structural heart, kidney, brain, and musculoskeletal differences. RREB1 haploinsufficiency and consequent abnormal RAS‐MAPK pathway signaling have been proposed as a driver of the disease phenotype; however, apart from a single case report, the phenotype of ...

Quality of Life of Families Who Have Children With Cornelia de Lange Syndrome in Brazil: Opportunities for Improvement

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT This exploratory cross‐sectional study aimed to estimate the family quality of life (FQoL) among 70 Brazilian families with children with Cornelia de Lange syndrome (CdLS). Data were collected using sociodemographic and clinical data forms, the Barthel index for activities of daily living, and the Beach Center FQoL Scale, a 5‐point Likert tool

Patient With Prolidase Deficiency due to an Homozygous PEPD Variant, Induced by Paternal Uniparental Isodisomy of Chromosome 19

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Uniparental disomy (UPD) is a rare phenomenon in which both copies of a chromosome are inherited from a single parent. This can lead to genomic imprinting disorders and recessive disorders due to the presence of recessive pathogenic variants in both alleles. Additionally, depending on the mechanisms by which UPD occurs, mosaic aneuploidies may

Long‐Read Whole‐Genome Sequencing Uncovers a Deletion Upstream to HOXD13 Causing Synpolydactyly

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Synpolydactyly (SPD) is a heterogeneous distal‐limb malformation syndrome, characterized by webbing and duplication of adjacent digits. SPD1, the most common type, is attributed to disease‐causing variants in HOXD13, a transcription factor in the HOXD cluster that is essential for limb development. Here, we present a challenging exome‐negative

A companion to the preclinical common data elements for rodent models of pediatric acquired epilepsy: A report of the TASK3‐WG1B, Pediatric and Genetic Models Working Group of the ILAE/AES Joint Translational Task Force

Epilepsia Open, EarlyView., 2022
Abstract Epilepsy syndromes during the early years of life may be attributed to an acquired insult, such as hypoxic–ischemic injury, infection, status epilepticus, or brain trauma. These conditions are frequently modeled in experimental rodents to delineate mechanisms of epileptogenesis and investigate novel therapeutic strategies.

Chromosome 3q22.2‐q26.2 Interstitial Deletion in a Patient With Wisconsin Syndrome, Blepharophimosis‐Ptosis‐Epicanthus Inversus Syndrome, Dandy‐Walker Malformation, Pierre Robin Sequence, and Recurrent Infections

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Wisconsin syndrome is a very rare genetic condition characterized by coarse facies, prominent nasal tip, bushy high arched/upsweeping eyebrows, and a full/everted lower lip. Deletion of chromosome 3q24q25 region is considered critical for its manifestation.

Severe Nerve Enlargement in SOS2‐Related Noonan Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan syndrome is a genetic multisystem congenital disorder, caused by pathogenic variants in genes that encode components of the RAS/MAPK signaling pathway. Pathogenic variants in SOS2 represent less than 2% of cases with NS. The phenotype includes a particularly high prevalence (65%) of lymphatic disease. Recently, severe nerve enlargements
