Rapid and cost-effective method for the detection of the c.533G>A mutation in the HEXA gene.

Abstract excerpt

Tay-Sachs disease is a rare autosomal recessive neurodegenerative disorder that results from mutations in the HEXA gene, leading to β-hexosaminidase A (HexA) α subunit deficiency. An unusual variant of Tay-Sachs disease is known as the B1 variant. Previous studies indicated that, in northern Portugal, this is not only the most common variant but also one of the most prevalent lysosomal storage diseases....
