Pathogenic, criteria provided, single submitter | clinical testing | Neuberg Centre For Genomic Medicine, NCGM | May 20, 2023 | The missense variant c.563C>T(p.Ser188Phe) in G6PD gene has been observed in individual(s) with G6PD deficiency (Thedsawad A, et. al., 2022;Arunachalam AK, et. al., 2020; AlJaouni et.al., 2011; Jamornthanyawat et. al., 2014). Experimental studies have shown that this missense change affects G6PD function (Molouet. al., 2014). It is commonly reported in individuals of Mediterranean, Middle Eastern, or Indian ancestry (AlJaouni et. al., 2011;Jamornthanyawat et. al., 2014). The observed variant has been reported with allele frequency of 0.2 % in gnomAD database. This variant has been reported to the ClinVar database as Likely Pathogenic / Pathogenic (multiple submitters). Computational evidence (Polyphen -Benign , SIFT - damaging and MutationTaster -disease causing) predicts conflicting evidence on protein structure and function for this variant. The amino acid change p.Ser188Phe in G6PD is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Ser at position 188 is changed to a Phe changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 31, 2024 | This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 188 of the G6PD protein (p.Ser188Phe). This variant is present in population databases (rs5030868, gnomAD 1.7%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with G6PD deficiency (PMID: 1978554, 8611726, 15315792, 16119988, 22018328, 24586352). It is commonly reported in individuals of Mediterranean, Middle Eastern, or Indian ancestry (PMID: 1978554, 8611726, 15315792, 16119988, 22018328, 24586352). ClinVar contains an entry for this variant (Variation ID: 100057). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt G6PD protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects G6PD function (PMID: 3393536, 22906047, 24460025). For these reasons, this variant has been classified as Pathogenic. - |

Likely pathogenic, criteria provided, single submitter | clinical testing | 3billion | Sep 01, 2022 | The variant is observed at an allele frequency greater than expected for the associated disorder in the gnomAD v2.1.1 dataset. However, this variant is the most common cause of G6PD deficiency in the Mediterranean area, the Middle East and the India subcontinent (ClinVar ID: VCV000100057). Missense changes are a common disease-causing mechanism. Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 22906047 , 24460025 , 3393536). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.81; 3Cnet: 0.49). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. - |

Pathogenic, criteria provided, single submitter | clinical testing | Lifecell International Pvt. Ltd | - | This variant in exon 6 of the G6PD gene results in the amino acid substitution from Serine to Phenylalanine at codon 188 (p.Ser188Phe) with the sequence change of c.653C>T (NM_000402.4). This variant was observed in a proband with decreased level of G6PD enzyme (<2.4 U/dL) which was screened for advanced newborn screening with confirmatory genetic reflex testing at lifecell diagnostics. This variant is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. The reference base is conserved across the species and in-silico predictions by Polyphen and SIFT are damaging. This variant has previously been reported for Anemia, Nonspherocytic Hemolytic, Due to G6pd Deficiency by T J Vulliamy et al., 1988. The Missense Variants Z-Score for this variant is 2.60. Missense Variants Z-Score is produced by the Exome Aggregation Consortium (60,706 adult humans) by computing a signed Z score for the deviation of observed counts from the expected number. Positive Z scores indicate increased constraint (intolerance to variation) and therefore that the gene had fewer missense variants than expected. This variant has been reported six individuals in homozygous condition, in 109 individuals in hemizygous condition and 25 individuals in heterozygous conditions. (Hellani et al. 2009; PMID: 19594365), (Moiz et al. 2012; PMID: 22906047), (Santana et al. 2013; PMID: 23479361), (Molou et al. 2014; PMID: 24460025) and (Jamornthanyawat et al. 2014; PMID: 24586352). - |

Pathogenic, criteria provided, single submitter | clinical testing | ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories | Nov 03, 2023 | The G6PD c.563C>T; p.Ser188Phe variant (rs5030868), also known as G6PD Mediterranean, is reported in the literature in multiple individuals affected with hemolytic anemia, hyperbilirubinemia and G6PD deficiency (Hellani 2009, Jamornthanyawat 2014, Kaplan 1997, Moiz 2012, Molou 2014, Vulliamy 1988). Functional analyses of the variant protein shows decreased enzyme activity, increased affinity for G6P and decreased in vitro thermostability (Moiz 2012, Molou 2014, Vulliamy 1988). This variant is reported in ClinVar (Variation ID: 100057). This variant is found predominantly in the South Asian population with an allele frequency of 1.7% (331/19,078 alleles, including 4 homozygotes and 211 hemizygotes) in the Genome Aggregation Database. The serine at codon 188 is moderately conserved, but computational analyses predict that this variant is deleterious (REVEL: 0.811). Based on available information, this variant is considered to be pathogenic. References: Hellani A et al.

G6PD deficiency Pathogenic:3
Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Oct 05, 2023 | Variant summary: G6PD c.653C>T (p.Ser218Phe) results in a non-conservative amino acid change located in the Glucose-6-phosphate dehydrogenase, C-terminal domain (IPR022675) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0026 in 183257 control chromosomes in the gnomAD database, including 6 homozygotes. This variant has a high frequency in South Asian population (0.017) in gnomAD. c.653C>T (Also known as G6PD Mediterranean) is a common cause of G6PD deficiency in the Mediterranean area, the Middle East and the India subcontinent (Kurdi-Haidar_1990). c.653C>T has been reported in the literature in multiple individuals affected with severe Glucose 6 Phosphate Dehydrogenase Deficiency (Kurdi-Haidar_1990), neonatal hyperbilirubinaemia (Moiz_2012) and hemolytic anemia (examples: Vulliamy_1988, Similuk_2022, and Naofal_2023). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in <10% of normal activity (Vulliamy_1988). The following publications have been ascertained in the context of this evaluation (PMID: 36703223, 35753512, 22906047, 3393536, 1978555). Thirty submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |
