ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.3900861).
BS1
Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.000196 (286/1461242) while in subpopulation NFE AF= 0.000253 (281/1111784). AF 95% confidence interval is 0.000228. There are 2 homozygotes in gnomad4_exome. There are 114 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High Homozygotes in GnomAdExome4 at 2 AR gene

The c.1186G>A (p.G396R) alteration is located in exon 12 (coding exon 11) of the MEIOB gene. This alteration results from a G to A substitution at nucleotide position 1186, causing the glycine (G) at amino acid position 396 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
