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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 05, 2024The c.146C>T (p.P49L) alteration is located in exon 4 (coding exon 2) of the HAO2 gene. This alteration results from a C to T substitution at nucleotide position 146, causing the proline (P) at amino acid position 49 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
