A Novel Constitutional TUBB Variant Associated With Familial Malformations of Cortical Development

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Most pathogenic tubulin variants arise de novo in sporadic patients, causing severe brain malformations and significant neurodevelopmental impairment. The resulting reproductive disadvantage typically prevents these mutations from being transmitted to offspring.

Longitudinal Echocardiographic Surveillance of Aortic Dilation in a Phenotype‐Enriched Turner Syndrome Cohort

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Turner syndrome (TS) is associated with thoracic aortopathy and increased risk for aortic dissection, yet the natural history of aortic dilation is not well understood. We performed a retrospective longitudinal study of individuals with TS who participated in the TS Society of the United States Healthy Heart Project between 2003 and 2023 ...

Severe Headbanging Responsive to Levodopa in a Child With FOXP1 Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We report a 9‐year‐old female with FOXP1 syndrome due to a de novo in‐frame deletion in the FOXP1 gene. The child has a severe neurodevelopmental disorder including global developmental delay and autism spectrum disorder. At age 2, she developed severe headbanging, which was progressive and did not respond to multidisciplinary, behavioral ...

The Diagnosis That Arrived Decades Late: Living Without and Then With Myhre Syndrome

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome (MIM #139210) is a rare multisystem disorder first described in 1981, characterized by short stature, neurodevelopmental delay, joint contractures, and cardiopulmonary complications. Its molecular basis, recurrent pathogenic variants in SMAD4, was not discovered until 2011. This narrative is based on a review of medical records,

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.

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.

A Novel Splice Variant in ERGIC1 Causes Arthrogryposis Multiplex Congenita—Characterization Using Urine‐Derived Cells

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Arthrogryposis multiplex congenita (AMC) is defined as the presence of joint contractures affecting at least two body regions at birth. Three different ERGIC1 variants have been reported in individuals with AMC. Here, we report on a 16‐year‐old male with a homozygous ERGIC1 c.250+1G>A variant that was classified as a variant of uncertain ...

Posthumously Diagnosed Myhre Syndrome Presenting With Pleural Remodeling and Endometrial Cancer

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome (OMIM 139210) is a genetic condition defined by neurodevelopmental disability, characteristic facial features, and multisystem proliferative fibrosis. While various types of lung disease have been reported, pleural remodeling leading to restrictive lung disease has not yet been described.
