Genes affected
KIF1A (HGNC:888): (kinesin family member 1A) The protein encoded by this gene is a member of the kinesin family and functions as an anterograde motor protein that transports membranous organelles along axonal microtubules. Mutations at this locus have been associated with spastic paraplegia-30 and hereditary sensory neuropathy IIC. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Apr 2012]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 20, 2020 | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C65"). This variant has not been reported in the literature in individuals with KIF1A-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with proline at codon 1170 of the KIF1A protein (p.His1170Pro). The histidine residue is highly conserved and there is a moderate physicochemical difference between histidine and proline. - |
