Mutations in a single copy of SNAI2 have also been found to cause patches of hair depigmentation without any other symptoms. [25] Type 2E is caused by an autosomal dominant mutation in the gene SOX10. [4] Rarely, a mutation in a gene other than those currently known may be responsible for a Waardenburg syndrome with features of type 2.
In contrast, mutations in the gene BAP1 are strongly linked to metastatic spread and patient survival. [17] Incidence of posterior uveal melanoma is highest among people with light skin and blue eyes. Other risk factors, such as blue light exposure and arc welding, have been put forward, but are still debated in the field.
Has only been partially researched and documented. It is caused by mutation of the tyrosinase-related protein-1 (Tyrp1) gene. Cases have been reported in Africa and New Guinea. Affected individuals typically have red hair, reddish-brown skin and blue or gray eyes. Variants may include rufous oculocutaneous albinism (ROCA or xanthism). The ...
P protein, also known as melanocyte-specific transporter protein or pink-eyed dilution protein homolog, is a protein that in humans is encoded by the oculocutaneous albinism II (OCA2) gene. [5] The P protein is believed to be an integral membrane protein involved in small molecule transport, specifically of tyrosine —a precursor of melanin .
The trial, involving 586 patients, tested the drug against chemotherapy in patients with non-small cell lung cancer (NSCLC) who had a specific gene mutation leading to abnormal cell growth. The ...
Multiple endocrine neoplasia type 2B (MEN 2B) is a genetic disease that causes multiple tumors on the mouth, eyes, and endocrine glands.It is the most severe type of multiple endocrine neoplasia, [2] differentiated by the presence of benign oral and submucosal tumors in addition to endocrine malignancies.

Ocular albinism type 1 (OA1) is the most common type of ocular albinism, with a prevalence rate of 1:50,000. [1] [2] It is an inheritable classical Mendelian type X-linked recessive disorder wherein the retinal pigment epithelium lacks pigment while hair and skin appear normal.
