Description

This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Arg1378*) 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 premature translational stop signal has been observed in individual(s) with hereditary spastic paraplegias (PMID: 24833714, 27217339). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 458283).
