Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4BS1_Supporting

The ENST00000315264.7(KIF26A):c.-48C>T variant causes a 5 prime UTR premature start codon gain change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000026 in 1,612,420 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).

Genes affected

KIF26A (HGNC:20226): (kinesin family member 26A) Predicted to enable microtubule binding activity and microtubule motor activity. Predicted to be involved in enteric nervous system development; negative regulation of signal transduction; and regulation of cell growth by extracellular stimulus. Predicted to be located in cytosol. Predicted to be part of kinesin complex. Predicted to be active in microtubule. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.39588585).

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000024 (35/1460258) while in subpopulation MID AF = 0.000693 (4/5768). AF 95% confidence interval is 0.000236. There are 0 homozygotes in GnomAdExome4. There are 18 alleles in the male GnomAdExome4 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
