ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.04002139).

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000193 (282/1458102) while in subpopulation MID AF= 0.00208 (12/5758). AF 95% confidence interval is 0.0012. There are 1 homozygotes in gnomad4_exome. There are 148 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

The c.307G>A (p.A103T) alteration is located in exon 4 (coding exon 4) of the EMC10 gene. This alteration results from a G to A substitution at nucleotide position 307, causing the alanine (A) at amino acid position 103 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
