Decoding the Genetic Mysteries of Aniridia and Atypical Aniridia
Not every case traces to PAX6: a homozygous 11p13 deletion sparing the gene and its enhancers was reported, which is why broad genetic screening matters.
Decoding Anterior Segment Anomalies and Cataract: Understanding, Diagnosing, and Genetic Testing
Cornea, iris and lens malformations with cataract are assessed by eye examination and imaging, while HMX1, FOXC1 and PAX6 are among the genes that may be tested.
Unlocking the Mysteries of Apparent Mineralocorticoid Excess: Mild Form
A homozygous HSD11B2 mutation affects the enzyme balancing mineralocorticoids, producing low-renin hypertension, low potassium levels and metabolic alkalosis.
Arylsulfatase A Pseudodeficiency or MLD? Telling Them Apart
Reduced ARSA activity without disease marks the pseudodeficiency allele. Genetic testing separates it from metachromatic leukodystrophy and finds carriers.
Decoding Arylsulfatase A Pseudodeficiency: Understanding, Diagnosing, and Genetic Testing
Discover the role of genetic testing in diagnosing Arylsulfatase A pseudodeficiency, understanding its connection to metachromatic leukodystrophy & managing risks.
Unlocking the Mysteries of Arylsulfatase A Pseudodeficiency and Its Severe Form
Most people with reduced arylsulfatase A activity have no symptoms, yet unusual variants are tied to metachromatic leukodystrophy, which testing detects.
Decoding Aspartylglucosaminuria: Understanding the Finnish Type and Genetic Testing
Developmental delay, coarse facial features and skeletal changes follow AGA enzyme deficiency; targeted, exon or full gene sequencing confirms the Finnish type.
