Genes affected

KIFC2 (HGNC:29530): (kinesin family member C2) Predicted to enable microtubule binding activity and microtubule motor activity. Predicted to be involved in microtubule-based movement and mitotic spindle assembly. Predicted to be located in cytoplasm. Predicted to be part of kinesin complex. Predicted to be active in microtubule cytoskeleton and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

KIFC2 links:

FOXH1 (HGNC:3814): (forkhead box H1) FOXH1 encodes a human homolog of Xenopus forkhead activin signal transducer-1. FOXH1 protein binds SMAD2 and activates an activin response element via binding the DNA motif TGT(G/T)(T/G)ATT. [provided by RefSeq, Jul 2008]

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
