Insights

Miller-Dieker syndrome (MDS) infants may develop retinopathy of prematurity-like proliferative peripheral retinopathy (PPR). Early ophthalmic exams and molecular testing are crucial for sight-saving interventions in lissencephaly patients.

Area of Science:

  • Genetics
  • Ophthalmology
  • Developmental Biology

Background:

  • Miller-Dieker syndrome (MDS) is a lissencephaly associated with a 17p13.3 microdeletion.
  • Ophthalmic examinations are not standard for infants diagnosed with MDS.
  • Co-occurring genetic anomalies can influence phenotypic presentation.

Observation:

  • Four cousins with MDS and a 16p13.3 microduplication were studied.
  • Two male cousins presented with retinopathy of prematurity-like proliferative peripheral retinopathy (PPR).
  • PPR varied in severity, with one case requiring surgical intervention.

Findings:

  • Proliferative peripheral retinopathy (PPR) was observed in male infants with MDS and 16p13.3 microduplication.
  • The ocular findings highlight a potential link between specific genetic deletions/duplications and retinal abnormalities.
  • Early detection of PPR is critical for timely management.

Implications:

  • Routine ophthalmic screening in infants with MDS and other lissencephalies is recommended.
  • Early molecular genetic testing alongside ophthalmologic exams can facilitate prompt diagnosis and treatment.
  • This case series emphasizes the importance of comprehensive evaluations for syndromic conditions with potential ocular manifestations.

Protein Families

Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism.   Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members.   If these new proteins contain similar amino acids in key...

Gene Families01:57

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Proliferative Phase01:20

Proliferative Phase

The proliferative phase typically occurs after menstruation and lasts between 6 to 13 days in a standard 28-day cycle. This phase involves the reconstruction of the endometrium, guided by estrogen produced by the developing ovarian follicle.
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...

Family Therapy

Family therapy conceptualizes psychological challenges as arising from dysfunctional interactions within the family unit, rather than as isolated issues within individuals. This approach seeks to address and transform the patterns of communication, roles, and relationships within families to promote healthier dynamics and emotional well-being for all members.
