Genes affected

TMEM70 (HGNC:26050): (transmembrane protein 70) This gene likely encodes a mitochondrial membrane protein. The encoded protein may play a role in biogenesis of mitochondrial ATP synthase. Mutations in this gene have been associated with neonatal mitochondrial encephalocardiomyopathy due to ATP synthase deficiency. Alternatively spliced transcript variants have been described.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.48).

BP6

Variant 8-73981300-C-A is Benign according to our data. Variant chr8-73981300-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 363690.

BP7

Synonymous conserved (PhyloP=0.019 with no splicing effect.

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000165 (241/1461858) while in subpopulation MID AF = 0.0026 (15/5768). AF 95% confidence interval is 0.0016. There are 1 homozygotes in GnomAdExome4. There are 145 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check.
