Genes affected

MICU3 (HGNC:27820): (mitochondrial calcium uptake family member 3) Predicted to enable calcium ion binding activity. Predicted to be involved in calcium import into the mitochondrion and mitochondrial calcium ion homeostasis. Predicted to be located in mitochondrial inner membrane. Predicted to be part of uniplex complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0176 (2676/152338) while in subpopulation NFE AF= 0.0289 (1966/68026). AF 95% confidence interval is 0.0278. There are 38 homozygotes in gnomad4. There are 1256 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 38 AR gene
