Clinical and genetic analysis of an early-onset sitosterolemia family caused by a novel compound heterozygous ABCG5 mutation.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences2026 Apr 01

Sitosterolemia (STSL) is a rare autosomal recessive disorder caused by biallelic mutations in ABCG5 or ABCG8, which encode sterolin efflux transporters. Defective transport leads to intestinal hyperabsorption and reduced biliary excretion of plant sterols and cholesterol, causing their accumulation and heterogeneous phenotypes often misdiagnosed as familial hypercholesterolemia. Whole-exome sequencing was performed in a 3-year-old child with early-onset hypercholesterolemia. Candidate variants were validated by Sanger sequencing of family members, followed by genotype-phenotype analysis. Plasma plant sterols were quantified by gas chromatography-mass spectrometry, and structural modeling was used to predict the impact of variants. The proband developed multiple xanthomas over the knees, elbows, ankles, finger joints and skin folds at 2 years of age. Her father and grandfather had obesity and hypercholesterolemia with fatty liver but no xanthomas. Genetic analysis identified a novel compound heterozygous ABCG5 mutation: c.1337G > A (p.Arg446Gln), inherited from the father and classified as likely pathogenic, and c.1396G > C (p.Ala466Pro), inherited from the mother and classified as a variant of uncertain significance according to ACMG guidelines. Segregation supported the genotype-phenotype correlation. Plasma sterol profiling showed elevated cholestanol, desmosterol, campesterol, stigmasterol and sitosterol with normal squalene and lathosterol. Ezetimibe plus a low-plant-sterol diet improved xanthomas and biochemical parameters. Structural modeling demonstrated conformational changes and reduced hydrogen bonding for both variants, suggesting impaired protein stability. The missense variants c.1337G > A (p.Arg446Gln) and c.1396G > C (p.Ala466Pro) in exon 10 of ABCG5 likely represent the molecular genetic basis of STSL in this family.

Sitosterolemia Presenting as Lipid Keratopathy and Xanthomas.

Pediatrics2026 Feb 01

Sitosterolemia is a rare autosomal recessive disorder of lipid metabolism, with varied incidence rates of 1/200 000 to 1/1 000 000. The condition often presents prepubertally, but is commonly misdiagnosed as familial hypercholesterolemia. We want to raise clinical suspicion across pediatric generalists and subspecialties with our case report of a 7-year-old girl who presented via ophthalmology following the surgical removal of a lipid keratopathy of her cornea. Four years before her presentation at ophthalmology, she also underwent surgical excision of a large xanthoma from her left buttock. There was no further diagnostic workup at that point. On examination, she had multiple tuberous xanthomas on her knuckles and knees in addition to the corneal deposits. Baseline lipid investigation revealed a markedly elevated total cholesterol of 11.9 mmol/L and an LDL cholesterol of 10.2 mmol/L. She was given a presumptive diagnosis of familial hypercholesterolemia and started on statin therapy, to which she had a partial response. Molecular genetic analysis for familial hypercholesterolemia was negative, but because of the high index of suspicion, an expanded genetics panel was requested that demonstrated compound heterozygous variants in the ABCG5 gene, pathogenic for sitosterolemia. Sterol analysis demonstrated markedly elevated phytosterol levels consistent with the genetic findings. The patient was treated with dietary restriction of plant sterols and Ezetimibe. Computed tomography coronary angiogram showed no coronary artery calcification. An awareness of sitosterolemia amongst pediatricians is vitally important as this condition may present to numerous specialties, as evidenced in this case. Recommended lifestyle and pharmacotherapy interventions differ between sitosterolemia and familial hypercholesterolemia.

Genetic dyslipidemias.

Annales d'endocrinologie2026 Mar 20

Although genetic factors strongly influence lipid metabolism, genetic dyslipidemias refer to specific monogenic defects that significantly alter the function of proteins involved in lipid metabolism. Familial hypercholesterolemia results from mutations in the genes coding for LDL receptor, apolipoprotein B100 (apoB100), PCSK9, or LDLRAP1. The rare homozygous form is severe, with extravascular lipid deposits at an early age and a high incidence of coronary events in childhood, in the absence of early diagnosis. The heterozygous form is more frequent and characterized by elevated plasma LDL cholesterol levels (>190 mg/dL in adults) and a very high risk of premature coronary artery disease (usually before the age of 50 years). Familial chylomicronemia syndrome (FCS) is a major form of genetic hypertriglyceridemia caused by mutations in genes encoding lipoprotein lipase or one of its cofactors (apoC-II, apoA-V, GPIHBP1, or LMF1). Patients with FCS exhibit markedly elevated plasma triglyceride levels (>10 mmol/L) and are at high risk for acute pancreatitis. Congenital familial partial lipodystrophy and glycogen storage diseases are two other forms of genetic hypertriglyceridemia. In addition, other rare genetic dyslipidemias have been described in humans, including familial dysbetalipoproteinemia, abetalipoproteinemia, familial hypobetalipoproteinemia, familial combined hypolipidemia, sitosterolemia, and hypoalphalipoproteinemias.

Case report: The first report of a family with sitosterolemia in the Polish population.

Journal of clinical lipidology2026 Feb 19

Sitosterolemia is a rare autosomal recessive lipid disorder caused by mutations in the ABCG5 or ABCG8 genes, resulting in excessive intestinal absorption and impaired biliary excretion of plant sterols, which leads to their accumulation in plasma and tissues. Clinical manifestations include premature coronary artery disease, liver dysfunction, hepatosplenomegaly, and hematologic abnormalities. We report the first Polish family diagnosed with sitosterolemia. A 19-year-old male patient with severe hypercholesterolemia and resistance to statin therapy and his family members were examined, including biochemical and imaging studies, serum sterol assessment by gas chromatography-mass spectrometry, and genetic testing using next-generation sequencing of genes involved in lipid metabolism. The proband presented with total cholesterol of 8.0 mmol/L, low-density lipoprotein cholesterol of 5.80 mmol/L, high-density lipoprotein cholesterol of 1.24 mmol/L, and triglycerides of 2.38 mmol/L. Genetic analysis revealed 2 variants in the ABCG8 gene in the patient and his brother: a pathogenic variant c.1083G>A (p.Trp361Ter), present in the patient's father, and a variant of uncertain significance c.1534G>A (p.Gly512Arg), present in the patient's mother. Serum sterol concentrations in the patient were markedly elevated, including campesterol (139.8 µmol/L), stigmasterol (2.2 µmol/L), isofucosterol (56.9 µmol/L), and sitosterol (333.9 µmol/L). Introduction of ezetimibe therapy combined with a low-plant sterol diet resulted in improvement of the lipid profile. These findings highlight the role of genetic testing and serum sterol measurement in the differential diagnosis of inherited lipid disorders, especially in patients with statin-resistant hypercholesterolemia. Early diagnosis of sitosterolemia is important to introduce an appropriate diet and pharmacotherapy.
