Genes affected

HAO2 (HGNC:4810): (hydroxyacid oxidase 2) This gene is one of three related genes that have 2-hydroxyacid oxidase activity. The encoded protein localizes to the peroxisome has the highest activity toward the substrate 2-hydroxypalmitate. Alternative splicing results in multiple transcript variants.

Ambry Genetics

Dec 07, 2021

The c.590C>T (p.T197I) alteration is located in exon 6 (coding exon 4) of the HAO2 gene. This alteration results from a C to T substitution at nucleotide position 590, causing the threonine (T) at amino acid position 197 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
