Hypogonadism genetic causes of hearing – Wolfram syndrome

This syndrome is characterized by hypergonadotropic hypogonadism, intellectual deficit, congenital skeletal anomalies involving the cervical spine and superior ribs, and diabetes mellitus. MIRAGE syndrome is an acronym for the major findings of myelodysplasia, infection, restriction of growth, adrenal hypoplasia, genital phenotypes, and enteropathy.

Introduction

Affected females are usually diagnosed at birth because of the pseudohermaphroditism. Mayo Clinic does not endorse companies or products. When onset is in early childhood, hearing loss can be progressive. POLG-related disorders comprise a continuum of overlapping phenotypes that were clinically defined long before their molecular basis was known. Almost all the people affected with syndrome experience blood in their urine i.

If a lactose-restricted diet is provided during the first ten days of life, the neonatal signs usually quickly resolve and the complications of liver failure, sepsis, and neonatal death are prevented; however, despite adequate treatment from an early age, children with classic galactosemia remain at increased risk for developmental delays, speech problems termed childhood apraxia of speech and dysarthriaand abnormalities of motor function. The effects — and what you can do about them — depend on the cause and at what point in your life male hypogonadism occurs. Most affected individuals have some, but not all, of the features of a given phenotype; nonetheless, the following nomenclature can assist the clinician in diagnosis and management.
