Genes affected

PGM3 (HGNC:8907): (phosphoglucomutase 3) This gene encodes a member of the phosphohexose mutase family. The encoded protein mediates both glycogen formation and utilization by catalyzing the interconversion of glucose-1-phosphate and glucose-6-phosphate. A non-synonymous single nucleotide polymorphism in this gene may play a role in resistance to diabetic nephropathy and neuropathy. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]

PGM3 links:

DOP1A (HGNC:21194): (DOP1 leucine zipper like protein A) Predicted to be involved in Golgi to endosome transport and endoplasmic reticulum organization. Predicted to be located in Golgi membrane. Predicted to be active in endosome and trans-Golgi network. [provided by Alliance of Genome Resources, Apr 2022]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 17, 2022	This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 566 of the PGM3 protein (p.Pro566Thr). This variant is present in population databases (rs143654268, gnomAD 0.08%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with PGM3-related conditions. ClinVar contains an entry for this variant (Variation ID: 252565). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	Molecular Genetics, Royal Melbourne Hospital	Apr 05, 2022	This sequence change in PGM3 is predicted to replace proline with threonine at codon 538, p.(Pro538Thr). The proline residue is evolutionarily conserved (100 vertebrates, UCSC), and is not located in a known functional domain. There is a small physicochemical difference between proline and threonine. The highest population minor allele frequency in gnomAD v2.1 is 0.09% (110/128,980 alleles, 1 homozygote) in the European (non-Finnish) population. This variant has been reported as a variant of uncertain significance (ClinVar ID: 252565), and to our knowledge has not been reported in the literature in any individuals with immunodeficiency. Multiple lines of computational evidence predict a deleterious effect for the missense substitution (5/6 algorithms). Based on the classification scheme RMH Modified ACMG Guidelines v1.4.0, this variant is classified as a VARIANT OF UNCERTAIN SIGNIFICANCE. Following criteria are met: PP3. -
