Concurrent Germline RB1 & Mosaic TP53 in a Child With Multiple Childhood Cancers

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We report a patient with a pathogenic germline variant (PGV) in RB1 and somatic mosaicism for a pathogenic TP53 variant who developed three distinct types of childhood cancer: retinoblastoma, osteosarcoma, and myelodysplastic syndrome (MDS) before the age of 6 years.

Systematic Cardiac Phenotyping of Patients With Copy Number Variants in the 15q11.2 Breakpoint 1 to Breakpoint 2 Region: A Retrospective Cohort Study From Nine Pediatric Cardiac Centers

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Microdeletions impacting 15q11.2 breakpoint (BP) 1 to BP2, adjacent to the Prader–Willi critical region, have previously described neuropsychiatric associations, with potential low penetrance presentations of congenital heart disease (CHD) also identified.

Milestone Attainment in Young Children With Arthrogryposis Multiplex Congenita: Developmental Profile and Associated Factors

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Evidence on developmental milestones in children with arthrogryposis multiplex congenita (AMC) under the age of five is scarce. This multisite cross‐sectional study described developmental status and examined factors associated with milestone attainment in 143 children aged 0–66 months from a pediatric AMC Registry.

Spectrum of Congenital Anomalies in Myhre Syndrome—Insights Into Effects Brought by Altered TGF‐β Signaling via Gain‐of‐Function Variants in SMAD4

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome is a rare genetic disorder characterized by progressive multisystem involvement. Gain‐of‐function missense heterozygous variants affecting the Ile500 residue and Arg496 residue of the SMAD4 gene are implicated in this condition.

Therapy for Myhre Syndrome: Goals, Misconceptions, and Current Agents

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre Syndrome (MYHRS, MIM #139210) is a rare, multisystem connective tissue disorder caused by recurrent heterozygous gain‐of‐function pathogenic variants in the SMAD4 gene, a key player in TGF‐β signaling and a regulator of extracellular matrix homeostasis.

Review of the Molecular and Developmental Basis of Myhre Syndrome, Bench Research

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome (MS) is a connective‐tissue disorder within the acromelic dysplasia spectrum. It is characterized by congenital craniofacial, skeletal, cutaneous anomalies, respiratory, cardiovascular along with intellectual disability, deafness, and progressive fibrosis.
