Genes affected

RPIA (HGNC:10297): (ribose 5-phosphate isomerase A) The protein encoded by this gene is an enzyme, which catalyzes the reversible conversion between ribose-5-phosphate and ribulose-5-phosphate in the pentose-phosphate pathway. This gene is highly conserved in most organisms. The enzyme plays an essential role in the carbohydrate metabolism. Mutations in this gene cause ribose 5-phosphate isomerase deficiency. A pseudogene is found on chromosome 18. [provided by RefSeq, Mar 2010]

RPIA links:

EIF2AK3 (HGNC:3255): (eukaryotic translation initiation factor 2 alpha kinase 3) The protein encoded by this gene phosphorylates the alpha subunit of eukaryotic translation-initiation factor 2, leading to its inactivation, and thus to a rapid reduction of translational initiation and repression of global protein synthesis. This protein is thought to modulate mitochondrial function. It is a type I membrane protein located in the endoplasmic reticulum (ER), where it is induced by ER stress caused by malfolded proteins. Mutations in this gene are associated with Wolcott-Rallison syndrome. [provided by RefSeq, Sep 2015]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.37).

BP6

Variant 2-88691710-C-T is Benign according to our data. Variant chr2-88691710-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 748412.Status of the report is criteria_provided_single_submitter, 1 stars.

BP7

Synonymous conserved (PhyloP=-0.133 with no splicing effect.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000263 (4/152356) while in subpopulation SAS AF = 0.000414 (2/4834). AF 95% confidence interval is 0.0000728. There are 0 homozygotes in GnomAd4. There are 3 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
