ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.27037877).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000198 (3/151786) while in subpopulation EAS AF= 0.000582 (3/5152). AF 95% confidence interval is 0.000158. There are 0 homozygotes in gnomad4. There are 0 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.20C>T (p.P7L) alteration is located in exon 1 (coding exon 1) of the KIF26A gene. This alteration results from a C to T substitution at nucleotide position 20, causing the proline (P) at amino acid position 7 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
