Genes affected

ZFYVE26 (HGNC:20761): (zinc finger FYVE-type containing 26) This gene encodes a protein which contains a FYVE zinc finger binding domain. The presence of this domain is thought to target these proteins to membrane lipids through interaction with phospholipids in the membrane. Mutations in this gene are associated with autosomal recessive spastic paraplegia-15. [provided by RefSeq, Oct 2008]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg728*) in the ZFYVE26 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ZFYVE26 are known to be pathogenic (PMID: 18394578, 19805727). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with hereditary spastic paraplegia with thin corpus callosum (PMID: 19805727). ClinVar contains an entry for this variant (Variation ID: 553395). For these reasons, this variant has been classified as Pathogenic. -
