Variant summary
Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1
The NM_004168.4(SDHA):c.1969G>A(p.Val657Ile) variant causes a missense change. The variant allele was found at a frequency of 0.128 in 1,605,264 control chromosomes in the GnomAD database, including 11,138 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V657L) has been classified as Uncertain significance.

Mitochondrial complex II deficiency, nuclear type 1 Benign:2
Benign, criteria provided, single submitter | clinical testing | Mendelics | May 28, 2019 | - - |
Benign, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 13, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. - |

not specified Benign:1
Likely benign, no assertion criteria provided | clinical testing | Genetic Services Laboratory, University of Chicago | - | Likely benign based on allele frequency in 1000 Genomes Project or ESP global frequency and its presence in a patient with a rare or unrelated disease phenotype. NOT Sanger confirmed. - |

Hereditary cancer-predisposing syndrome Benign:1
Benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 18, 2014 | 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. - |
SDHA-related disorder Benign:1
Benign, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Jun 02, 2022 | This variant is classified as benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). - |
