Description
The p.E113* pathogenic mutation (also known as c.337G>T), located in coding exon 4 of the LDLR gene, results from a G to T substitution at nucleotide position 337. This changes the amino acid from a glutamic acid to a stop codon within coding exon 4. This alteration, also known as p.E92*, has been reported in patients with familial hypercholesterolemia (FH) (Hobbs HH et al. Hum. Mutat., 1992;1:445-66; Jensen HK et al. Atherosclerosis, 1999 Oct;146:337-44; Szalai C et al. Clin. Genet., 1999 Jan;55:67-8; Weiss N et al. J. Inherit. Metab. Dis., 2000 Dec;23:778-90; Salazar LA et al. Hum. Mutat., 2002 Apr;19:462-3). This alteration has also been reported in a homozygous state in a pediatric FH cohort (Sanna C et al. Atherosclerosis, 2016 Apr;247:97-104). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
