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.

Aug 17, 2021

The c.773T>C (p.I258T) alteration is located in exon 7 (coding exon 5) of the HAO2 gene. This alteration results from a T to C substitution at nucleotide position 773, causing the isoleucine (I) at amino acid position 258 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
