Overview
It is thought that Hutchinson-Gilford progeria is the result due to mutation in LMNA gene.
Pathophysiology
Pathogenesis
- It is understood that Hutchinson-Gilford progeria is the result due to mutation in LMNA gene.[1]
Genetics
Genes involved in the pathogenesis of Hutchinson-Gilford progeria syndrome (HGPS) include:
LMNA Gene
- The location of the Hutchinson-Gilford progeria syndrome (HGPS) gene was in chromosome 1q[2]
- A single nucleotide substitution in the lamin A/C gene LMNA(c.1824C>T [p.Gly608Gly]) results in classic HGPS[3]
- De novo dominant mutation in the LMNA gene causes classic HGPS
- A single de novo dominant mutation at C to T pathogenic variant at located in exon 11, C1824T of the LMNA gene results in activation of a cryptic splice donor site[4]
- The mutation does not change the position of glycine at 608 in protein chain
- The resultant of the mutation leads to formation of short lamin A protein which is called progerin
