21. NOAH — Information For Students Writing A Report On Albinism We’re delighted you’re doing a report on albinism, one of the most interesting, yet often misunderstood, genetic phenomena. The majority of the materials NOAH http://www.albinism.org/faq/report.html

Information for Students Assigned a Report on Albinism What is albinism? Where can I find facts about albinism? What do people with albinism look like? What is it like to have albinism? ... I Read EVERYTHING here and I still have questions about albinism. How can I contact NOAH? What is albinism? Albinism is a group of genetic conditions that causes a lack of pigment. It can effect only the eyes (ocular albinism) or both the eyes and skin (oculocutaneous albinism). Most types of albinism are inherited when an individual receives the albinism gene from both parents. The exception is one type of ocular albinism, which is passed on from mothers to their sons. For more information on the genetics of albinism, see the NOAH Information Bulletin What is Albinism Top Where can I find facts about albinism? Top What do people with albinism look like? While most people with albinism have very light skin and hair, not all do. In less pigmented types of oculocutaneous albinism, (the type of albinism that affects both the skin and the eyes), hair and skin are cream-colored. In types with slight pigmentation, hair appears more yellow or red-tinged People with ocular albinism (albinism that only affects the eyes) usually have normal or only slightly lighter than normal physical appearance. A common myth is that by definition people with albinism have red eyes. In fact there are different types of albinism, and the amount of pigment in the eyes varies. Most individuals with albinism have blue eyes. Some have hazel or brown eyes. See

Contact Us Search MedlinePlus Health Topics ESPAÑOL Albinism Albinism is a defect of melanin production that results in little or no color (pigment) in the skin, hair, and eyes. Causes Albinism occurs when one of several genetic defects makes the body unable to produce or distribute melanin, a natural substance that gives color to your hair, skin, and iris of the eye. The defects may be passed down through families. There are two main types of albinism: Type 1 albinism is caused by defects that affect production of the pigment, melanin. Type 2 albinism is due to a defect in the "P" gene. People with this type have slight coloring at birth. The most severe form of albinism is called oculocutaneous albinism. People with this type of albinism have white or pink hair, skin, and iris color, as well as vision problems. Another type of albism, called ocular albinism type 1 (OA1), affects only the eyes. The person's skin and eye colors are usually in the normal range. However, an eye exam will show that there is no coloring in the back of the eye (retina). Hermansky-Pudlak syndrome (HPS) is a form of albinism caused by a single gene. It can occur with a bleeding disorder, as well as with lung and bowel diseases.

DOJ Contents Syndromic albinism: A review of genetics and phenotypes Noah S Scheinfeld MD JD Dermatology Online Journal 9 (5): 5 From the Department of Dermatology, St. Luke's-Roosevelt Hospital Center and Beth Israel Medical Center, New York. scheinfeld@earthlink.net Abstract There are several syndromes of albinism associated with systemic pathology. These include Chediak-Higashi Syndrome (CHS), Hermansky-Pudlack Syndrome (HPS), Griscelli Syndrome (GS), Elejalde Syndrome (ES) and Cross-McKusick-Breen Syndrome (CMBS). In the last several years the genetic defects underlying some of these syndromes have been described. HPS is related to 7 genes in humans. GS is related to 3 genes: MYOVA, Rab-27A, and melanophilin (Mlph). CHS is related to one gene: LYST. The genetic defects in ES and CMBS are yet to be defined. Syndromic forms of albinism are associated with defects in the packaging of melanin and other cellular proteins. As such they are distinct from oculocutaneous albinism, which is associated with defects in the production of melanin (e.g., TRP1, P gene, and tyrosinase). There are several syndromes of albinism associated with systemic pathology. These include Chediak-Higashi Syndrome (CHS), Hermansky-Pudlack Syndrome (HPS), Griscelli Syndrome (GS), Elejalde Syndrome (ES), and Cross-McKusick-Breen Syndrome (CMBS). In the last several years, genetic defects underlying some of these syndromes have been described (Table 1). Moreover, variants and novel clinical phenotypes have been described as well. The common etiologic element of these syndromes seems to involve defective formation of secretory vesicles and lysosomes. This article reviews these syndromes with particular attention on newly described genetic defects and phenotypes.

Probability of Inheritance The value of studying genetics is in understanding how we can predict the likelihood of inheriting particular traits. This can help plant and animal breeders in developing varieties that have more desirable qualities. It can also help people explain and predict patterns of inheritance in family lines. One of the easiest ways to calculate the mathematical probability of inheriting a specific trait was invented by an early 20th century English geneticist named Reginald Punnett . His technique employs what we now call a Punnett square . This is a simple graphical way of discovering all of the potential combinations of genotypes that can occur in children, given the genotypes of their parents. It also shows us the odds of each of the offspring genotypes occurring. Setting up and using a Punnett square is quite simple once you understand how it works. You begin by drawing a grid of perpendicular lines: Next, you put the genotype of one parent across the top and that of the other parent down the left side. For example, if parent pea plant genotypes were YY and GG respectively, the setup would be: Note that only one letter goes in each box for the parents. It does not matter which parent is on the side or the top of the Punnett square.

About this guide Produced with the help of the Royal College of Ophthalmologists About nystagmus Nystagmus is an uncontrolled movement of the eyes, usually from side to side, but sometimes the eyes swing up and down or even in a circular movement. Most people with nystagmus have reduced vision. Types of nystagmus Nystagmus that appears in the first months of life is called "early onset nystagmus" or "congenital nystagmus". The condition may also develop later in life when the term "acquired nystagmus" is used. Causes of nystagmus Nystagmus in early childhood may be caused by a problem with the eye or visual pathway from the eye to the brain. It occurs in a wide range of eye conditions of childhood such as cataract, glaucoma, some conditions of the retina and albinism (see "Related eye conditions" later in this document). It may also be found in children who have multiple disabilities such as Down's syndrome. Many children with nystagmus do not have eye, brain or other health problems. In this case the condition is called "congenital idiopathic nystagmus" or "idiopathic nystagmus", meaning that the condition starts very early on in life and the cause is unknown.

Home Contact Site Map Home ... A Albinism (Hypopigmentation, Oculocutaneous albinism, Ocular albinism) Definition: Causes: Albinism is rare. In the United States about 1 in 17,000 inidividuals overall has some form of albinism. All races are affected, though Type 1 occurs predominantly in whites and Type 2 in blacks. Most children with albinism are born to parents with normal hair and skin color for their ethnic background. While albinism is always apparent at birth, it may be so mild that affected persons are unaware of their diagnosis unless abnormal eye movements or vision develop. Risk Factors: A risk factor is something that increases your chances of getting a disease or condition. Albinism is a hereditary disorder. Therefore, people at risk of inheriting albinism are: Children of parents who have albinism Children of parents who do not have albinism, but carry the altered genes that cause this disorder A positive family history for albinism in a sibling or other relative Puerto Rican anscestry (this significantly increases the risk of an otherwise rare form of albinism known as Hermansky-Pudlak syndrome).

Practice Problems Genetics In a cross between a black and a white guinea pig, all members of the FI generation are black. The F2 generation is made up of approximately 3/4 black and Y4 white guinea pigs. Diagram this cross (punnett square) showing the genotypes and phenotypes. What will the offspring be like if two F2 white guinea pigs are mated? (Remember! F 1 = parents; F1 first offspring; F2 offspring from F1) In guinea pigs, the allele for rough coat (R) is dominant over the allele for smooth coat (r). In order for all the offspring to be smooth coated, what should the genotype and phenotype of the male and female parents be? (use punnett square). In rabbits, the allele for black coat color (B) is dominant over the allele for brown coat color (b). What would be the results of a cross between an animal homozygous for black coat color (BB) and one homozygous for brown coat color (bb)? Use punnett Square to determine both genotypic and phenotypic ratios? Albinism in humans is a simple autosomal recessive trait. For the following families, determine the genotypes of the parents and offspring. When 2 alternative genotypes are possible, list both.
