Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BS1 BS2

The NM_015241.3(MICAL3):​c.2248A>C​(p.Met750Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0226 in 1,602,090 control chromosomes in the GnomAD database, including 459 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0016676784).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.025 (3809/152302) while in subpopulation AFR AF= 0.0342 (1420/41572). AF 95% confidence interval is 0.0327. There are 62 homozygotes in gnomad4. There are 1844 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 62 AR gene
