20-21161882-C-G

Variant summary

Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1

The NM_018474.6(KIZ):ā€‹c.417C>Gā€‹(p.His139Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.656 in 1,607,958 control chromosomes in the GnomAD database, including 352,336 homozygotes. In-silico tool predicts a benign outcome for this variant. 10/13 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (ā˜…ā˜…). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt. Synonymous variant affecting the same amino acid position (i.e. H139H) has been classified as Likely benign.

Genes affected
KIZ (HGNC:15865): (kizuna centrosomal protein) The protein encoded by this gene localizes to centrosomes, strengthening and stabilizing the pericentriolar region prior to spindle formation. The encoded protein usually remains with the mother centrosome after centrosomal duplication. Sevral transcript variants encoding different isoforms have been found for this gene.
