ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.10468072).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000092 (14/152130) while in subpopulation AFR AF= 0.00029 (12/41398). AF 95% confidence interval is 0.000167. There are 0 homozygotes in gnomad4. There are 8 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Collection Method: clinical testing

The c.313C>T (p.L105F) alteration is located in exon 3 (coding exon 3) of the KIF26A gene. This alteration results from a C to T substitution at nucleotide position 313, causing the leucine (L) at amino acid position 105 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
