Undiagnosed metabolic disorders v1.609 ATP5E Sarah Leigh Gene: atp5e has been classified as Green List (High Evidence).
Undiagnosed metabolic disorders v1.607 PIGM Sarah Leigh changed review comment from: A single PIGM variant (NM_145167.2(PIGM):c.-270C>G) has been associated with Glycosylphosphatidylinositol deficiency, (OMIM:610293) and as limited Gen2Phen gene for the same condition.
To date, this variant has only been reported in people of Arab or Turkish descent. Microsatellite- and SNP-based haplotypes encompassing PIGM reported in PMID:19168132, suggested that a founder effect in the two families (one Arab and one Turkish) was unlikely. However, subsequent occurrences of the variant in two additional unrelated Arab families (PMID: 31445883) might suggest that this variant is confined within the Middle Eastern populations.
Functional studies have shown that this variant reduces transcription of PIGM and blocks mannosylation of glycosylphosphatidylinositol anchor (PMID: 16767100).; to: A single PIGM variant (NM_145167.2(PIGM):c.-270C>G)(rs587776528) has been associated with Glycosylphosphatidylinositol deficiency, (OMIM:610293) and as limited Gen2Phen gene for the same condition.

Undiagnosed metabolic disorders v1.603 SEC23B Arina Puzriakova Added comment: Comment on mode of inheritance: There is limited evidence linking this gene with Cowden syndrome (monoallelic variants).

Undiagnosed metabolic disorders v1.551 SDHA Arina Puzriakova Added comment: Comment on mode of inheritance: This gene was recently included on a gene list provided by Carl Fratter (Oxford University Hospitals NHS Trust) on behalf of GMS Mitochondrial providers, indicating that the MOI should be updated from 'biallelic' only to 'both mono- and biallelic' on Mitochondrial GMS panels (R354 and R63).

Undiagnosed metabolic disorders v1.440 GLS Arina Puzriakova Classified gene: GLS as Amber List (moderate evidence)
Undiagnosed metabolic disorders v1.440 GLS Arina Puzriakova Added comment: Comment on list classification: Upgraded from Red to Amber. There are sufficient cases, supported by functional data, to rate this gene Green - however, detection of the 5' UTR triplet expansion (PMID:30970188) must first be validated within the Genomics England pipeline.

When excluding cases with the STR, the remaining evidence is not sufficient for inclusion as diagnostic-grade and therefore keeping Amber until the STR is validated or additional cases arise.

Undiagnosed metabolic disorders v1.417 ALG14 Sarah Leigh Added comment: Comment on list classification: Associated with Myasthenic syndrome, congenital, 15, without tubular aggregates 616227 in OMIM, but not associated with phenotype in Gen2Phen. At least 6 variants reported in at least 5 cases with varying phenotypes. PMID 23404334 reports compound heterozygous (p.P65L, P.R104*) sibs, who manifested with myasthenic syndromes, but did not have intellectural disability nor seizures and were 62 and 51 years old when reported. PMID 28733338 reports two compound heterozygous (p.D74N, pV141G), (p.D74N, p.R109Q) cases and a homozygous (p.D74N), with early and lethal neurodegeneration with myasthenic and myopathic features, but the cases died before intellectual disability was manifiest. However, seizures were evident in two compound heterozygous families. PMID 30221345 reports a homozygous splicing variant in a case with intellectual disability and seizures. Functional studies were presented showing that this variant resulting in exon skipping, however, this was not completely prenetrant as wild type protein was detected at a low level in the patient.

Undiagnosed metabolic disorders v1.357 FDX2 Sarah Leigh Added comment: Comment on list classification: Based on reviews from Carl Fratter and Zornitza Stark (below).
This gene was added as Green due to the overall review and evidence assessment from the GMS mitochondrial specialist test group, submitted by Carl Fratter (May 2019) on behalf of GMS mitochondrial specialist test group: 3 unrelated familties; iron sulfur pathway. From panel: Possible mitochondrial disorder - nuclear genes (Version 0.187).
Promoted from red to amber, based on the expert review by Zornitza Stark (Australian Genomics) and the literature. FDX2 is associated with a phenotype in OMIM and not Gene2Phenotype. PMID: 24281368 describes a patient born of consanguineous Jewish Moroccan patents with episodic mitochondrial myopathy without optic atrophy or reversible leukoencephalopathy. The authors identified a homozygous missense variant in this gene (M1L). PMID: 30010796 describes 6 patients from 2 apparently unrelated Brazilian familes from the same geographical region with episodic mitochondrial myopathy. All affected individuals had the same homozygous variant (P144L). No haplotype analysis was performed. As there are only 2 different variants reported in this gene and no haplotype analysis was performed in PMID: 30010796 it was decided that there is currently not enough evidence to promote this gene to green status.

Undiagnosed metabolic disorders v1.82 RPIA Sarah Leigh commented on gene: RPIA: Review by Konstantinos Varvagiannis for the Genetic Epilepsy syndromes panel. 9 Dec 2018, 1:44 a.m.
Panel version: 0.1488
Biallelic pathogenic variants in RPIA cause Ribose 5-phosphate isomerase deficiency, MIM 608611. PMID: 14988808 is the first report on the disorder with molecular (incl. genetic) confirmation of the diagnosis. A patient initially investigated for early developmental delay, leukoencephalopathy, seizures with onset at 4 years, with subsequent neurologic regression and peripheral neuropathy at the age of 7, was suspected to have a disorder of the pentose phosphate pathway on the basis of highly elevated polyols on brain MRS and body fluid analysis. Reduced ribose 5-phosphate isomerase activity was shown in fibroblasts. Genetic testing demonstrated the presence of a missense (NM_144563.2:c.404C>T or p.Ala135Val - previously referred to as A61V) as well as a frameshift variant (NM_144563.2:c.762delG or p.Asn255Ilefs). Additional extensive supportive functional studies were published a few years later (PMID: 20499043). [This patient was initially described in PMID: 10589548]. PMID: 28801340 is a report on a second patient. This individual presented with delayed early development (independent walking and speech achieved at 2 and 5 years respectively), seizures and regression at the age of 7 with MRI white matter abnormalities. Review of magnetic resonance spectroscopy (MRS) was suggestive of elevated polyols (arabitol and ribitol). In line with this, genetic testing revealed a homozygous missense variant in RPIA (NM_144563.2:c.592T>C or p.Phe198Leu). Urine analysis confirmed elevated excretion of polyols, thus confirming the diagnosis. PMID: 30088433 reports on a boy with neonatal onset leukoencephalopathy and developmental delay having undergone early metabolic testing and aCGH (the latter at the age of 16 months). Persistance of his delay motivated exome sequencing at the age of approx. 4.5 years which demonstrated 2 RPIA variants (NM_144563.2:c.253G>A or p.Ala85Thr and NM_144563.2:c.347-1G>A). Measurement of ribitol and arabitol in urine demonstrated significant elevations (>20x) consistent with this diagnosis. 2 of the 3 patients described in the literature presented seizures. As a result this gene can be considered for inclusion in this panel as amber. [This gene is also present in the Undiagnosed metabolic disorders gene panel as red.
