Pleiotropy01:33

Pleiotropy

43.7K
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,...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

4.7K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Nephrotic Syndrome I : Introduction

789
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

    Area of Science:

    • Genetics
    • Dermatology
    • Rare Diseases

    Background:

    • Papillon-Lefevre syndrome is a rare autosomal recessive disorder.
    • Key features include palmoplantar hyperkeratosis and periodontitis.
    • Nail abnormalities are less commonly reported but can occur.

    Purpose of the Study:

    • To describe the clinical presentation of two siblings with Papillon-Lefevre syndrome.
    • To highlight the specific nail findings in these patients.
    • To contribute to the understanding of phenotypic variability in Papillon-Lefevre syndrome.

    Main Methods:

    • Case report of two affected siblings.
    • Clinical examination focusing on dermatological and nail findings.
    • Review of existing literature on Papillon-Lefevre syndrome.

    Main Results:

    • Both siblings exhibited the characteristic palmoplantar hyperkeratosis.
    • Uniquely, both presented with symmetrical, progressive hyperkeratosis and dystrophy affecting all fingernails and toenails.
    • No significant periodontitis was noted in this pair.

    Conclusions:

    • Papillon-Lefevre syndrome can manifest with significant nail dystrophy alongside classic symptoms.
    • The symmetrical and progressive nature of the nail changes in this case is noteworthy.
    • Further research is needed to elucidate the genetic and clinical factors influencing nail involvement in this syndrome.
