Pleiotropy

43.4K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Sex-linked Disorders01:43

Sex-linked Disorders

109.4K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

X-linked Traits01:19

X-linked Traits

59.0K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

Incomplete Dominance01:43

Incomplete Dominance

30.2K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

    Summary

    Congenital Brown syndrome often presents with horizontal misalignment requiring surgical correction. Addressing this deviation during surgery improves outcomes for affected patients.

    Area of Science:

    • Ophthalmology
    • Pediatric Ophthalmology
    • Strabismus Surgery

    Background:

    • Congenital Brown syndrome is a rare condition affecting eye movement.
    • Horizontal deviations can coexist with Brown syndrome, impacting binocular vision.

    Purpose of the Study:

    • To determine the incidence of horizontal deviations needing surgical correction in congenital Brown syndrome patients.
    • To evaluate the necessity of addressing horizontal misalignment during Brown syndrome surgery.

    Main Methods:

    • Retrospective review of 16 patients with congenital Brown syndrome undergoing surgery (1998-2016).
    • Analysis of preoperative primary position horizontal misalignment and surgical interventions.
    • Assessment of horizontal deviation before and after surgical correction.

    Main Results:

    • 56% of patients had preoperative horizontal deviation (exodeviations and one esotropia).
    • 50% of patients underwent surgery for horizontal deviation correction, with significant reduction postoperatively.
    • Superior oblique tendon weakening procedures were common, with Z-tenectomy being most frequent.

    Conclusions:

    • Congenital Brown syndrome frequently involves significant horizontal misalignment.
    • Surgical correction of horizontal deviations should be considered in patients with congenital Brown syndrome.
