Likely inborn error of metabolism - targeted testing not possible
Gene: RNASEH2A
I note these genes have been demoted - whilst they may not have a metabolic biochemical phenotype of themselves, they appear in the differential diagnosis of a child with a suspected metabolic, especially mitochondrial/white matter disorder - and it is increasingly common for WGS to be used early in the evaluation of these patients. With the development of inherited white matter disease services it is appropriate for some genes like those for AGS to appear in both R98 and R109 in my opinion.

RNASEH2A is associated with Aicardi-Goutieres syndrome 4 on OMIM and Gene2Phenotype. There are >3 unrelated cases on OMIM supporting the gene-disease link between RNASEH2A with Aicardi-Goutieres syndrome; however, RNASEH2A does not appear to be associated with a metabolic phenotype. Therefore this gene has been demoted to red.Created: 20 Sep 2019, 9:12 a.m. | Last Modified: 20 Sep 2019, 9:18 a.m.
