FH Gene Sequencing & Del/Dup
Genes
Conditions
- Fumarate Hydratase Deficiency
- Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC)
Clinical Utility
- An individual with a personal history of features associated with autosomal dominant hereditary leiomyomatosis and renal cell cancer (HLRCC, also referred to as Reed syndrome), especially cutaneous leiomyomas (smooth muscle tumors of the skin), symptomatic and/or multiple uterine leiomyomas (fibroids) before age 40 years, and/or tubulo-papillary, collecting-duct, or papillary type II renal cell carcinoma
- An individual with a personal and/or family history of features associated with autosomal recessive fumarate hydratase deficiency, such as excessive urinary excretion of fumurate, neonatal hypotonia, growth and developmental delay, seizures, structural brain malformations, severe neurologic impairment, dysmorphic facial features, and neonatal polycythemia
- An unaffected individual with a family history suggestive of HLRCC (see above) when an affected individual is unavailable for his or her own genetic testing
Lab Method
