Genes affected

CERT1 (HGNC:2205): (ceramide transporter 1) This gene encodes a kinase that specifically phosphorylates the N-terminal region of the non-collagenous domain of the alpha 3 chain of type IV collagen, known as the Goodpasture antigen. Goodpasture disease is the result of an autoimmune response directed at this antigen. One isoform of this protein is also involved in ceramide intracellular transport. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

CERT1 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.
