14-67762745-A-T

Position:

• chr14-67762745-A-T

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_015346.4(ZFYVE26):​c.6086T>A​(p.Ile2029Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I2029T) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 33)
• Consequence: ZFYVE26 NM_015346.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 9.32

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]

ZFYVE26 (HGNC:):
