Lymphedema-distichiasis (LD) is a dominantly inherited syndrome with onset of lymphedema at or just after puberty. Most affected individuals have distichiasis-fine hairs arising inappropriately from the eyelid meibomian glands-which is evident from birth. A study of three families with LD has shown linkage to chromosome 16q24.3, and subsequent analysis of the region for recombinant genes places the locus between D16S422 and D16S3074, a distance of approximately 16 cM. Possible candidate genes in this interval include the N-proteinase for type 3 collagen, PCOLN3; the metalloprotease PRSM1; and the cell matrix-adhesion regulator, CMAR.

Article Synopsis
  • - The study investigates the prenatal and postnatal features, along with genetic traits, of Lymphedema-Distichiasis syndrome (LDS) in two Chinese families with FOXC2 gene mutations.
  • - Genetic analysis revealed pathogenic variants in the FOXC2 gene for both families, with literature review yielding a total of 117 identified LDS patients, including prenatal signs in 13 cases and postnatal manifestations in 110.
  • - Key prenatal symptoms of LDS include increased nuchal translucency and fetal edema, while postnatal symptoms commonly feature distichiasis and lymphedema, with only a few cases exhibiting signs before and after birth.

Pharmacological inhibition of FOXO1 promotes lymphatic valve growth in a congenital lymphedema mouse model.

Article Synopsis
  • * The transcription factor FOXO1 inhibits the formation of lymphatic valves by suppressing valve-forming gene expression, making it a potential target for lymphedema treatments.
  • * The FOXO1 inhibitor AS1842856 was shown to significantly boost valve-forming gene expression in human lymphatic endothelial cells and increased the number of lymphatic valves in a mouse model of lymphedema, suggesting it may be an effective approach for treating valve defects.

Article Synopsis
  • A fetus was identified with a 2.12-Mb deletion on chromosome 16, leading to two serious conditions: alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV) and lymphedema-distichiasis syndrome (LDS).
  • The fetus showed multiple structural abnormalities during an ultrasound at around 24 weeks of gestation, prompting genetic testing through amniocentesis.
  • The results revealed a deletion indicating a genetic issue, emphasizing the need for genomic testing as a primary diagnostic approach for fetuses with structural problems.

Article Synopsis
  • Lymphedema-dissociated syndrome (LDS) is a condition linked to mutations in the FOXC2 gene, which have unclear effects on its development.
  • The study examined mutations in FOXC2 found in two Chinese families, using various lab techniques to analyze their impact on gene function and lymphatic vessel formation.
  • Results showed that several mutations led to reduced DNA binding and transcription abilities, affecting key pathways like ERK-RAS and Wnt4 signaling, potentially explaining some developmental issues associated with LDS.

Article Synopsis
  • - Distichiasis is a condition where an extra row of eyelashes grows from the meibomian gland openings, either from congenital conditions like lymphedema distichiasis syndrome or secondary to issues like cicatrizing conjunctivitis.
  • - The review discusses the causes, symptoms, and the evolution of surgical treatments for distichiasis, highlighting that while various treatment options exist, success rates are often between 50%-60%, especially for acquired cases.
  • - Treatments like electroepilation and cryotherapy are less effective compared to surgical excision, with better outcomes noted for methods like marginal tarsectomy; however, the exact nature of distichiasis lashes and their management remains inadequately understood.
