Insights

This case report details a newborn diagnosed with piebaldism and café-au-lait macules (CALMs). Early diagnosis and counseling are crucial for managing this rare genetic skin condition.

Area of Science:

  • Dermatology
  • Clinical Genetics
  • Pediatrics

Background:

  • Piebaldism is a rare autosomal dominant disorder characterized by congenital, benign, white macules and patches due to melanocyte absence.
  • Café-au-lait macules (CALMs) are common hyperpigmented birthmarks that can be associated with various genetic syndromes.

Observation:

  • A 45-day-old infant presented with asymptomatic, depigmented macules since birth, notably rhomboid-shaped on the abdomen and lower extremities.
  • The infant also exhibited a depigmented forehead macule with leukotrichia and three hyperpigmented CALMs on the chest.

Findings:

  • Clinical examination revealed characteristic depigmented macules and CALMs, leading to a diagnosis of piebaldism with CALMs.
  • No consanguinity or significant family history was reported, and the infant was otherwise developing normally.

Implications:

  • This case highlights the importance of recognizing piebaldism and associated CALMs in neonates.
  • Genetic counseling is essential to discuss potential risks of associated syndromes like Legius syndrome or neurofibromatosis type 1 (NF1) and plan for regular follow-up.

Epistasis01:39

Epistasis

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Pleiotropy01:33

Pleiotropy

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,...
