Understanding Verloes–David Syndrome and Its Variants

Introduction to Verloes–David Syndrome

The Verloes–David Syndrome, also known as the Verloes–David–Pfeiffer Syndrome, is a progressive skeletal disorder with severe limb deformities․

The Verloes–David Syndrome, also known as the Verloes–David–Pfeiffer Syndrome, is a progressive skeletal disorder characterized by severe limb deformities․ Although the genetic basis involves mutations in multiple genes, the FLNB gene mutations are not typically associated with this syndrome․

Definition and Overview

The Verloes–David Syndrome is a progressive skeletal disorder characterized by severe limb deformities due to genetic mutations in multiple genes․

FLNB Gene Mutations

No mutations in the FLNB gene have been identified in individuals with Verloes–David Syndrome․ The genetic basis of this syndrome involves mutations in multiple genes, excluding the FLNB gene typically linked to other conditions․

Autosomal Dominant Inheritance

Verloes–David Syndrome follows an autosomal dominant pattern of inheritance, where a mutation in a single copy of the gene associated with the syndrome is sufficient to cause the condition․ This means that individuals with one affected parent have a 50% chance of inheriting the syndrome․

Clinical Features of Verloes–David Syndrome

The clinical features of Verloes–David Syndrome include progressive skeletal abnormalities and associated craniofacial anomalies․

Skeletal Abnormalities

Individuals with Verloes–David Syndrome exhibit progressive skeletal abnormalities, including severe limb deformities characterized by mesomelic shortness of stature with acral synostoses, umbilical anomalies, and soft palate agenesis․

Associated Craniofacial Anomalies

Verloes–David Syndrome is characterized by associated craniofacial anomalies, which may include ptosis, hypertelorism, palatal abnormality, congenital heart disease, and ureteral anomalies, in addition to the progressive skeletal abnormalities․

Radiological Abnormalities in Verloes–David Syndrome

Radiological abnormalities play a crucial role in differentiating Verloes–David Syndrome from other related syndromes, aiding in accurate diagnosis and treatment planning․

Differentiation from Other Syndromes

Radiological abnormalities are instrumental in distinguishing Verloes–David Syndrome from other related syndromes, facilitating accurate diagnoses and treatment plans․ These abnormalities provide crucial insights into the unique expression of this syndrome and aid in distinguishing it from syndromes with overlapping features․

Mesomelia-Synostoses Syndrome⁚ A Variant of Verloes–David Syndrome

Mesomelia-Synostoses Syndrome, also known as MES, is a variant of Verloes–David Syndrome characterized by mesomelic limb shortening and acral synostoses, presenting a rare autosomal-dominant disorder․

Description and Characteristics

The Mesomelia-Synostoses Syndrome, a variant of Verloes-David Syndrome, is characterized by mesomelic limb shortening, acral synostoses, and multiple congenital malformations․ It presents as a rare autosomal-dominant disorder with distinctive clinical features․

Relationship to Other Genetic Syndromes

The Verloes-David-Pfeiffer Syndrome is closely related to Mesomelia-Synostoses Syndrome, an autosomal-dominant form of mesomelic dysplasia with distinct clinical features․

Association with ACTB and ACTG1 Mutations

Several genetic syndromes have been linked to gain-of-function mutations in the ACTB and ACTG1 genes, notably Baraitser-Winter, Fryns-Aftimos, and cerebrofrontofacial syndromes․ These mutations alter the expression of cytoplasmic actins, leading to distinct clinical presentations․

Rare Forms and Unique Phenotypes

Several unclassified forms of Verloes–David Syndrome have been reported, often in single families, exhibiting unique and distinct phenotypes․ In addition, the mesomelia-synostoses syndrome is a rare autosomal-dominant disorder with specific clinical features․

Unclassified Forms of Verloes–David Syndrome

Several unclassified forms of Verloes-David Syndrome have been reported, each with unique phenotypes, possibly involving unknown genetic causes․ These forms present challenges in classification and require further research to understand their distinct characteristics and underlying mechanisms․

Population Estimates and Frequency

The Verloes–David-Pfeiffer Syndrome is a rare autosomal-dominant disorder, with fewer than 1,000 known cases reported globally․

Incidence and Prevalence Data

The Verloes–David-Pfeiffer Syndrome is considered a rare autosomal-dominant disorder, with global reports indicating fewer than 1,000 documented cases, making it a relatively infrequent condition within the population․
