Genes affected

PRELP (HGNC:9357): (proline and arginine rich end leucine rich repeat protein) The protein encoded by this gene is a leucine-rich repeat protein present in connective tissue extracellular matrix. This protein functions as a molecule anchoring basement membranes to the underlying connective tissue. This protein has been shown to bind type I collagen to basement membranes and type II collagen to cartilage. It also binds the basement membrane heparan sulfate proteoglycan perlecan. This protein is suggested to be involved in the pathogenesis of Hutchinson-Gilford progeria (HGP), which is reported to lack the binding of collagen in basement membranes and cartilage. Alternatively spliced transcript variants encoding the same protein have been observed. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jul 30, 2023

The c.43G>A (p.A15T) alteration is located in exon 2 (coding exon 1) of the PRELP gene. This alteration results from a G to A substitution at nucleotide position 43, causing the alanine (A) at amino acid position 15 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
