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]

Uncertain significance, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	The ZFYVE26 c.273+8G>A splice region variant has been reported in one study in which it is found in a homozygous state in one individual with autosomal recessive spastic paraplegia (Yoon et al. 2013). Control data are unavailable for this variant, which is reported at a frequency of 0.00071 in the East Asian population of the Exome Aggregation Consortium. The evidence for this variant is limited. The c.273+8G>A variant is therefore classified as a variant of unknown significance but suspicious for pathogenicity for autosomal recessive spastic paraplegia. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -
