Genes affected
SLC25A22 (HGNC:19954): (solute carrier family 25 member 22) This gene encodes a mitochondrial glutamate carrier. Mutations in this gene are associated with early infantile epileptic encephalopathy. Multiple alternatively spliced variants, encoding the same protein, have been identified.[provided by RefSeq, Jul 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.77).
BP6
Variant 11-792955-C-T is Benign according to our data. Variant chr11-792955-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 139134.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=1, Likely_benign=3}. Variant chr11-792955-C-T is described in Lovd as [Likely_benign].
BP7
Synonymous conserved (PhyloP=-5.86 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000506 (77/152264) while in subpopulation AFR AF= 0.000746 (31/41560). AF 95% confidence interval is 0.000539. There are 0 homozygotes in gnomad4. There are 32 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

not specified Benign:1
Benign, criteria provided, single submitterclinical testingGeneDxMar 20, 2013This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Inborn genetic diseases Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsJul 11, 2016This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
