Uncertain significance, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	May 12, 2023	Variant summary: SLC25A22 c.151G>A (p.Asp51Asn) results in a conservative amino acid change in 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 0.00052 in 246498 control chromosomes, predominantly at a frequency of 0.007 within the African or African-American subpopulation in the gnomAD database. c.151G>A has been reported in the literature in the heterozygous state in an individual affected with juvenile myoclonic epilepsy (Lee_2018). This report does not provide unequivocal conclusions about association of the variant with Developmental And Epileptic Encephalopathy, 3. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 29924869). Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as benign (n=1)/likely benign (n=2) and VUS (n=1). Based on the evidence outlined above, the variant was classified as uncertain significance. -
Benign, criteria provided, single submitter	clinical testing	GeneDx	Jun 27, 2013	This 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. -

This alteration is classified as 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. -
