Modes of inheritance:
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.
 
Genes (locations): PAX6 (11p13); WT1 (11p13)

Disease characteristics

Excerpted from the GeneReview: PAX6-Related Aniridia
PAX6-related aniridia occurs either as an isolated ocular abnormality or as part of the Wilms tumor-aniridia-genital anomalies-retardation (WAGR) syndrome. Aniridia is a pan ocular disorder affecting the cornea, iris, intraocular pressure (resulting in glaucoma), lens (cataract and lens subluxation), fovea (foveal hypoplasia), and optic nerve (optic nerve coloboma and hypoplasia). Individuals with aniridia characteristically show nystagmus and impaired visual acuity (usually 20/100 - 20/200); however, milder forms of aniridia with subtle iris architecture changes, good vision, and normal foveal structure do occur. Other ocular involvement may include strabismus and occasionally microphthalmia. Although the severity of aniridia can vary between and within families, little variability is usually observed in the two eyes of an affected individual. WAGR syndrome. The risk for Wilms tumor is 42.5%-77%; of those who develop Wilms tumor, 90% do so by age four years and 98% by age seven years. Genital anomalies in males can include cryptorchidism and hypospadias (sometimes resulting in ambiguous genitalia), urethral strictures, ureteric abnormalities, and gonadoblastoma. While females typically have normal external genitalia, they may have uterine abnormalities and streak ovaries. Intellectual disability (defined as IQ <74) is observed in 70%; behavioral abnormalities include attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, anxiety, depression, and obsessive-compulsive disorder. Other individuals with WAGR syndrome can have normal intellect without behavioral issues. [from GeneReviews]

Additional description

From MedlinePlus Genetics
Intellectual disability and other developmental delays are also common in people with WAGR syndrome. Affected individuals often have difficulty processing, learning, and properly responding to information. Many affected individuals have difficulty speaking or understanding language. Some individuals with WAGR syndrome also have psychiatric or behavioral problems such as depression, anxiety, attention-deficit/hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), or a developmental disorder called autism spectrum disorder that affects communication and social interaction.

Other signs and symptoms of WAGR syndrome can include ongoing constipation, inflammation of the pancreas (pancreatitis), kidney failure, breathing problems, and allergies. Some affected children have obesity. When WAGR syndrome includes childhood-onset obesity, it is often referred to as WAGRO syndrome.

People with WAGR syndrome have a 45 to 60 percent chance of developing Wilms tumor, a rare form of kidney cancer. This type of cancer is most often diagnosed in children but is sometimes seen in adults. Some people with WAGR syndrome develop nephrogenic rests, which are abnormal clumps of cells in the kidneys. These can lead to Wilms tumor, but some people with nephrogenic rests never develop Wilms tumor.

Most people with WAGR syndrome have aniridia, an absence of the colored part of the eye (the iris). This can reduce the sharpness of a person's vision (visual acuity) and increase sensitivity to light (photophobia). Aniridia is typically the first noticeable sign of WAGR syndrome. Other eye problems may also develop, such as clouding of the lens of the eyes (cataracts), increased pressure in the eyes (glaucoma), and involuntary eye movements (nystagmus).

Abnormalities of the genitalia and urinary tract (genitourinary anomalies) are seen more frequently in males with WAGR syndrome than in affected females. The most common genitourinary abnormality in affected males is undescended testes (cryptorchidism). Affected females may not have functional ovaries and may instead have undeveloped clumps of tissue called streak gonads. Females with WAGR syndrome may also have a heart-shaped (bicornate) uterus, which makes it difficult to carry a pregnancy to term.

WAGR syndrome is a disorder that affects many body systems and is named for its main features: Wilms tumor, aniridia, genitourinary anomalies, and a range of developmental delays.  https://medlineplus.gov/genetics/condition/wagr-syndrome

Clinical features

From HPO
Nephroblastoma
MedGen UID:
10221
Concept ID:
C0027708
Neoplastic Process
The presence of a nephroblastoma, which is a neoplasm of the kidney that primarily affects children.
Gonadoblastoma
MedGen UID:
104912
Concept ID:
C0206661
Neoplastic Process
The presence of a gonadoblastoma, a neoplasm of a gonad that consists of aggregates of germ cells and sex cord elements.
Cryptorchidism
MedGen UID:
8192
Concept ID:
C0010417
Congenital Abnormality
Cryptorchidism, or failure of testicular descent, is a common human congenital abnormality with a multifactorial etiology that likely reflects the involvement of endocrine, environmental, and hereditary factors. Cryptorchidism can result in infertility and increases risk for testicular tumors. Testicular descent from abdomen to scrotum occurs in 2 distinct phases: the transabdominal phase and the inguinoscrotal phase (summary by Gorlov et al., 2002).
Kidney disorder
