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=-0.53).

BP7

Synonymous conserved (PhyloP=0.467 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0000723 (11/152208) while in subpopulation NFE AF = 0.000103 (7/68030). AF 95% confidence interval is 0.0000476. There are 0 homozygotes in GnomAd4. There are 4 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change affects codon 17 of the FOCAD mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the FOCAD protein. This variant is present in population databases (rs141452536, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with FOCAD-related conditions. ClinVar contains an entry for this variant (Variation ID: 2890238). Experimental studies and prediction algorithms are not available or were not evaluated, and the effect of this variant on mRNA splicing is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
