Ophthalmologic findings in an 18-month-old boy with focal dermal hypoplasia

Area of Science:

• Genetics
• Ophthalmology
• Developmental Biology

Background:

• Focal dermal hypoplasia (FDH) is a rare X-linked dominant disorder.
• Males typically experience in utero lethality due to the condition.
• Mutations in the PORCN gene at chromosome Xp11.23 are associated with FDH.

Observation:

• This report focuses on an 18-month-old boy with FDH.
• The patient presented with mosaicism for a newly identified mutation in the PORCN gene.
• Ophthalmologic findings were specifically evaluated.

Findings:

• The study describes the specific ophthalmologic manifestations observed in the patient.
• Mosaicism for a novel PORCN mutation was confirmed.
• Clinical correlation between the genetic findings and ocular presentation is discussed.

Implications:

• This case expands the understanding of PORCN gene mutations in FDH.
• It highlights the importance of ophthalmologic evaluations in affected individuals.
• Further research into genotype-phenotype correlations in FDH is warranted.
