RCV003447531 | SCV004175246 | pathogenic | Leukoencephalopathy-thalamus and brainstem anomalies-high lactate syndrome | 2022-12-19 | criteria provided, single submitter | clinical testing | The EARS2 c.212del variant is classified as Pathogenic (PVS1, PM2, PM3_supporting) This EARS2 c.212del variant is located in exon 2/9 and is predicted to cause a shift in the reading frame at codon 71, likely resulting in non-sense mediated decay of the protein product (PVS1). The variant is rare in population databases (gnomAD allele frequency = 0.0013%; 2 het and 0 hom in 152212 sequenced alleles) (PM2). This variant has been detected in trans with a likely pathogenic variant (c.320G>A) for this recessive condition (PM3_supporting). The variant has been reported in dbSNP (rs778413603) and has been reported as Likely pathogenic by other diagnostic laboratories (ClinVar Variation ID: 419276). It has not been reported in HGMD. |

RCV003447531 | SCV005086788 | pathogenic | Leukoencephalopathy-thalamus and brainstem anomalies-high lactate syndrome | 2023-07-17 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as pathogenic. The following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with combined oxidative phosphorylation deficiency 12 (MIM#614924). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD (v2) <0.01 for a recessive condition (4 heterozygotes, 0 homozygotes). (SP) 0803 - This variant has limited previous evidence of pathogenicity in unrelated individuals. This variant has previously been reported as likely pathogenic in ClinVar. (SP) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 0701 - Other NMD-predicted variants comparable to the one identified in this case have very strong previous evidence for pathogenicity (ClinVar). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
