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]

Labcorp Genetics (formerly Invitae), Labcorp

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Arg1602*) 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 present in population databases (rs558285072, gnomAD 0.008%). This premature translational stop signal has been observed in individuals with spastic paraplegia (PMID: 27544497; internal data). ClinVar contains an entry for this variant (Variation ID: 550774). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
