Variant 8-17027657-G-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_181723.3(MICU3):c.378G>C(p.Glu126Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000102 in 1,299,292 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E126A) has been classified as Uncertain significance.

Ambry Genetics

Jul 15, 2021

The c.378G>C (p.E126D) alteration is located in exon 1 (coding exon 1) of the MICU3 gene. This alteration results from a G to C substitution at nucleotide position 378, causing the glutamic acid (E) at amino acid position 126 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
