Fish Odor Syndrome: Urine and FMO3 Tests for Diagnosis

类别
Articles

TrimethylaminuriaUrine TestingGenetic Testing Fish odor syndrome is investigated by measuring urinary trimethylamine and trimethylamine N-oxide, sometimes on repeated samples. Selected FMO3 genetic testing can confirm inherited trimethylaminuria when the biochemical findings fit; odor alone cannot diagnose it.

Alport Syndrome Genetic Testing: Genes and Family Risk

类别
Articles

Alport SyndromeGenetic ResultsFamily Risk Alport syndrome genetic testing can establish a molecular diagnosis when pathogenic or likely pathogenic COL4A3, COL4A4 or COL4A5 findings fit the inheritance pattern. A variant of uncertain significance does not confirm Alport syndrome; confirmed findings help determine kidney surveillance, hearing and eye assessments, and which relatives need testing. Medically reviewed by […]
