Her family history included a diagnosis of NCAH in her sister (<span class="elsevierStyleItalic">Ile172Asn/Val281Leu</span> genotype). The mother and father were heterozygous carriers of the mutated <span class="elsevierStyleItalic">Val281Leu</span> and <span class="elsevierStyleItalic">Ile172Asn</span> alleles, respectively. The patient was under follow-up in the reproductive endocrinology clinic at our centre for NCAH - with the same genotype as her sister - diagnosed at another centre at 7 years and 10 months of age after presenting with premature pubarche with advanced bone age and acne. Hyperandrogenaemia was found, biochemically confirming the diagnosis of NCAH and subsequently the referred genotype. Treatment with hydrocortisone was started initially, with spontaneous menarche at 13 years of age. Given the lack of hyperandrogenaemia control, hydrocortisone was replaced by evening dexamethasone at 17 years of age. At the time she was transferred to our clinic aged 18, the patient was not overweight or obese, had reached her target height, reported regular menstruation, and had no dermo-cutaneous signs of hyperandrogenism. Mild suppression of the corticotropic axis was observed (serum cortisol after conventional stimulation with 1–24 ACTH of 12μg/dL), and therefore the glucocorticoid dose was progressively reduced until a sufficient functional reserve was observed for it to be discontinued, and she remained clinically asymptomatic. During her disease progression, at the age of 22, treatment was started with a combined oral contraceptive composed of ethinylestradiol (30μg) and dienogest (2<span class="elsevierStyleHsp" style=""></span>mg) for dysmenorrhoea. In various analyses performed during the 5 years of follow-up in our adult clinic, total circulating cholesterol <150−130<span class="elsevierStyleHsp" style=""></span>mg/dL was observed (this finding was already present in analyses performed at 16 years of age); LDL-cholesterol concentrations repeatedly <30<span class="elsevierStyleHsp" style=""></span>mg/dL, HDL-cholesterol between 80 and 110<span class="elsevierStyleHsp" style=""></span>mg/dL, and circulating triglycerides <40<span class="elsevierStyleHsp" style=""></span>mg/dL, for which reason referral was decided to a specialist clinic for familial dyslipidaemia.</p><p id="par0025" class="elsevierStylePara elsevierViewall">Targeted history taking showed that her 66-year-old father, with a history of hypertension and resolved HBV, was being followed up by the gastroenterology department for chronic diarrhoea with 5–6 watery stools per day, without pathological products with accompanying urgency, with histological data of lymphocytic colitis, as well as severe non-alcoholic hepatic steatosis, and under treatment with oral budesonide, resin-cholestyramine, loperamide on demand, and calcifediol due to vitamin D deficiency.

No known history of cardiovascular disease in the family. On re-anamnesis, the patient presented with non-specific gastrointestinal alterations with increased gastric motility as the only noteworthy finding. The analytical parameters of liver function and fat-soluble vitamin concentrations were within the normal range. However, given the abnormalities in the lipid profile (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>) and the family history, familial HBL was suspected, and a DNA study was performed on the patient, focusing on the coding region and adjacent intronic regions of the <span class="elsevierStyleItalic">APOB</span>, <span class="elsevierStyleItalic">ANGPTL3</span>, <span class="elsevierStyleItalic">PCSK9,</span> and <span class="elsevierStyleItalic">MTTP</span> genes by NGS using the Roche KAPA HyperChoice technology panel developed by the Institute of Medical and Molecular Genetics (INGEMM).

In obese patients, an increase in triglycerides and lower HDL levels have been reported, probably related to excess weight and hyperandrogenism.<a class="elsevierStyleCrossRefs" href="#bib0025"><span class="elsevierStyleSup">5,6</span></a> In any case, the patient presented a lipid pattern with excessively low LDL and triglyceride levels, which is not a classic presentation NCAH, in addition to fulfilling the criteria of Fredrikson et al.<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">10</span></a> for the diagnosis of HBL, that is, low plasma concentrations, absence of secondary causes explain this abnormality (malabsorption, malnutrition, severe infections, severe liver disease), and a potentially affected first-degree relative.</p><p id="par0045" class="elsevierStylePara elsevierViewall">In familial HBL, circulating concentrations of total cholesterol, LDL, ApoB, and sometimes triglycerides, are decreased below the fifth percentile of the reference population.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> In plasma ApoB is expressed in two forms: ApoB-100 and ApoB-48; both encoded by the APOB gene located on chromosome 2. ApoB-100 is expressed in the liver and is a component of VLDL, IDL and LDL; it also serves as a ligand for the LDL receptor. ApoB-48 is expressed in the intestine as part of chylomicrons.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a> ApoB-specific familial HBL the mutation is located in the <span class="elsevierStyleItalic">APOB</span> gene; production of premature stop codons in the mRNA is the most frequent mutation.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> Translation of these mRNAs leads to the formation of truncated ApoB that loses the ability to form plasma lipoproteins and, consequently, to export lipids from the liver and intestine to other organs. The detection of truncated ApoB in plasma suggests that the mutation is located from exon 26 to exon 29 of the <span class="elsevierStyleItalic">APOB</span> gene. Truncated ApoBs shorter than ApoB29-30, due to mutations located in the first 25 exons of the gene, are not secreted and therefore cannot be detected in plasma.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a> In the patient, a mutation was detected in exon 26 due to an amino acid change causing a premature codon stop and the generation of abnormal ApoB. The case’s parent had severe fatty liver disease, which is a frequent clinical manifestation in heterozygous patients. Due to the low production rate of unmutated ApoB-100 and impaired triglyceride transport, the VLDL export system for lipids is impaired,<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> causing the accumulation of lipids in the liver. In fact, recent evidence links familial HBL to the development of cirrhosis and hepatocellular carcinoma,<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> and it is advisable to monitor liver enzymes and perform imaging tests if these are elevated. Monitoring and follow-up are important, and the prognosis has been reported to be severe when the disease appears in early childhood and excellent for the moderate form without cytolysis or steatosis. However, in general, heterozygous subjects do not require any specific treatment, except for fat-soluble vitamin supplementation, if deficiency is detected, to avoid neurological complications. Stressing the fact that this condition is benign in most cases, this heterozygosity has been related to a prolonged life expectancy in probable relation to a lower risk of cardiovascular events.</p><p id="par0050" class="elsevierStylePara elsevierViewall">Our case is the first documented case of a combination of both genetic disorders. The remoteness of the responsible genes located on 2 different chromosomes rules out a joint inheritance pattern due to linkage disequilibrium. However, hypothesising any evolutionary advantage of such a combination may be controversial, beyond the longevity observed in some heterozygous subjects with ApoB-related familial HBL, given that there is no evidence that non-classical CAH impairs the survival of subjects with it. A potential decrease in circulating androgen and progestogen concentrations secondary to decreased cholesterol concentrations, such as that observed in the first case after statin administration in functional hyperandrogenism,<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">12</span></a> could be accompanied by an increase in fertility in these women. However, this assertion is purely speculative, especially since most women with NCAH conceive spontaneously, and functional hyperandrogenism could even be an evolutionary advantage per se.<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">13</span></a> However, studies that are not available in successive generations of this family may shed some light on the possible intra-familial association of these mutations, as has been observed in other diseases.<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">10</span></a></p></span><span id="sec0020" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0040">Conclusions</span><p id="par0055" class="elsevierStylePara elsevierViewall">We present the case of a patient with 2 genetic disorders inherited from her parents with an exceptional association.
