AI Article Synopsis

  • Distal Arthrogryposis type 5D (DA5D) is a genetic condition marked by joint contractures, short stature, and various physical traits, inherited in an autosomal recessive pattern linked to mutations in the ECEL1 gene.
  • Researchers reported two Sardinian patients with a new homozygous variant in ECEL1 that may disrupt mRNA splicing, potentially leading to the condition.
  • This study adds to the understanding of DA5D by documenting this rare variant and reviewing known mutations in the ECEL1 gene, enhancing the database of genetic causes.

Article Abstract

Distal Arthrogryposis type 5D (DA5D) is characterized by congenital contractures involving the distal joints, short stature, scoliosis, ptosis, astigmatism, and dysmorphic features. It is inherited in an autosomal recessive manner, and it is a result of homozygous or compound heterozygous variants in the ECEL1 gene. Here, we report two patients of Sardinian origin harboring a new intronic homozygous variant in ECEL1 (c.1507-9G>A), which was predicted to affect mRNA splicing by activating a cryptic acceptor site. The frequency of the variant is very low in the general human population, and its presence in our families can be attributed to a founder effect. This study provides an updated review of the known causative mutations of the ECEL1 gene, enriching the allelic spectrum to include the noncoding sequence.

Background: Arthrogryposis multiplex congenita involves joint contractures across various body parts. Distal arthrogryposis type 5D (DA5D) is a rare, autosomal recessive subtype affecting distal extremities, with symptoms like knee extension contractures, camptodactyly, overriding fingers, ulnar wrist deviation, and scoliosis.

Case: A 24-year-old pregnant woman with a second-degree relative partner had a fetus showing increased nuchal translucency (3.

Distal arthrogryposis type 5D (DA5D) is clinically characterized by knee extension contractures, distal joint contractures, clubfoot, micrognathia, ptosis, and scoliosis. We report nine affected individuals from eight unrelated Indian families with DA5D. Although the overall musculoskeletal phenotype is not very distinct from other distal arthrogryposis, the presence of fixed knee extension contractures with or without scoliosis could be an important early pointer to DA5D.

Article Synopsis
  • Distal arthrogryposis type 5D (DA5D) is a rare genetic condition that causes congenital joint contractures in the limbs, inherited in an autosomal recessive manner and linked to specific gene mutations.
  • A case study of a 6-month-old male infant revealed significant bilateral knee contractures and ptosis, with whole-exome sequencing identifying two novel compound heterozygous mutations related to the condition.
  • This case emphasizes the importance of molecular genetic screening for diagnosing rare disorders and expands the understanding of genetic mutations involved in DA5D.

Article Synopsis
  • ECEL1 is linked to an autosomal recessive form of distal arthrogryposis, and the study examined a novel mutation (c.535A>G) identified in a family with affected boys and fetus through prenatal testing.
  • Researchers conducted whole-exome sequencing and molecular dynamic simulations to analyze the differences between the normal and mutated ECEL1 proteins, validating the mutation presence in the affected family members.
  • The study found significant structural differences in the ECEL1 protein due to the mutation, particularly its inability to bind zinc ions, which contributes to the neurodegenerative disorder, suggesting the findings could enhance our understanding of the mutation's effects on the protein.

Background: Distal Arthrogryposis type 5D (DA5D) is a rare genetic disease, expressed phenotypically by skeletal and ocular abnormalities.

Materials And Methods: Two sisters, ages 42 and 46 years old, were ascertained, both diagnosed with arthrogryposis and unusual ophthalmic late expressions of the disease. They were examined and followed up by both ophthalmologists and medical geneticists.
