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.

The c.34C>T (p.H12Y) alteration is located in exon 3 (coding exon 1) of the HAO2 gene. This alteration results from a C to T substitution at nucleotide position 34, causing the histidine (H) at amino acid position 12 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
