Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 11P and 1B. PM1PP2PP5_Very_StrongBS2_Supporting

The NM_001360016.2(G6PD):c.392G>T(p.Gly131Val) variant causes a missense change. The variant allele was found at a frequency of 0.000019 in 1,210,297 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 3 hemizygotes in GnomAD. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G131E) has been classified as Uncertain significance.

Genes affected

G6PD (HGNC:4057): (glucose-6-phosphate dehydrogenase) This gene encodes glucose-6-phosphate dehydrogenase. This protein is a cytosolic enzyme encoded by a housekeeping X-linked gene whose main function is to produce NADPH, a key electron donor in the defense against oxidizing agents and in reductive biosynthetic reactions. G6PD is remarkable for its genetic diversity. Many variants of G6PD, mostly produced from missense mutations, have been described with wide ranging levels of enzyme activity and associated clinical symptoms. G6PD deficiency may cause neonatal jaundice, acute hemolysis, or severe chronic non-spherocytic hemolytic anemia. Two transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 10 ACMG points.

PM1

In a hotspot region, there are 11 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 8 uncertain in NM_001360016.2

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 185 curated pathogenic missense variants (we use a threshold of 10). The gene has 42 curated benign missense variants. Gene score misZ: 2.0008 (below the threshold of 3.09). Trascript score misZ: NaN (below the threshold of 3.09). GenCC associations: The gene is linked to anemia, nonspherocytic hemolytic, due to G6PD deficiency, class I glucose-6-phosphate dehydrogenase deficiency, G6PD deficiency.

PP5

Variant X-154535261-C-A is Pathogenic according to our data. Variant chrX-154535261-C-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 10404.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS2

High Hemizygotes in GnomAdExome4 at 2 XL geneVariant has number of hemizygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
