Genes associados
1 gene identificado com associação a esta condição. Padrão de herança: Autosomal recessive.
Oxidoreductase that catalyzes the last step of the cholesterol synthesis pathway, which transforms cholesta-5,7-dien-3beta-ol (7-dehydrocholesterol,7-DHC) into cholesterol by reducing the C7-C8 double bond of its sterol core (PubMed:25637936, PubMed:38297129, PubMed:38297130, PubMed:9465114, PubMed:9634533). Can also metabolize cholesta-5,7,24-trien-3beta-ol (7-dehydrodemosterol, 7-DHD) to desmosterol, which is then metabolized by the Delta(24)-sterol reductase (DHCR24) to cholesterol (By simila

Smith-Lemli-Opitz syndrome
An autosomal recessive frequent inborn disorder of sterol metabolism with characteristic congenital malformations and intellectual disability. Children with SLOS have elevated serum 7-dehydrocholesterol (7-DHC) levels and low serum cholesterol levels. SLOS occurs in relatively high frequency: approximately 1 in 20,000 to 30,000 births in populations of northern and central European background. Historically, a clinical distinction often was made between classic ('type I') SLOS and the more severely affected ('type II') patients. There is, in reality, a clinical and biochemical continuum from mild to severe SLOS.

Prenatal Fentanyl Exposure Association With Characteristic Neonatal Anomalies.
To investigate if previously described anomalies associated with fentanyl could be identified in our cohort of individuals with active fentanyl use in pregnancy. Potential cases of a novel syndrome were identified from a prospectively collected database of obstetric patients with substance use disorder enrolled in a multispecialty treatment program from 2014 to 2024 in this case series study. Suspected Fetal Fentanyl Syndrome (FFS) was defined as small head circumference (<10%ile) and at least one other sign: cleft palate, clubfoot, rocker bottom feet, toe syndactyly, single palmar crease, hypoplastic corpus callosum, and hypospadias. The database was screened for findings consistent with this syndrome resembling Smith-Lemli-Opitz Syndrome. From 2014 to 2024, 639 patients were enrolled in the cohort. Of the 103 patients found to have neonates with a small head circumference, 51 individuals self-reported fentanyl use within the last year. Six of these individuals had confirmatory toxicology testing for fentanyl upon program enrollment. Of these individuals' neonates, 4 displayed characteristic anomalies consistent with FFS. All cases shared lagging head growth, while additional anomalies identified included cleft palate (n=3), short nasal tip (n=1), thin upper lip (n=1), micrognathia (n=1), and hypospadias (n=1). Genetic screening/diagnostic testing varied but an assessment of cholesterol metabolism was not performed. In this cohort, 7.8% of individuals with self-reported fentanyl use had neonates with signs of the previously described FFS. FFS is a proposed syndrome and results should be interpreted with caution. Similar data is needed to confirm and delineate this association and determine long-term developmental effects.
Prevalence of Smith-Lemli-Opitz Syndrome Carriers and the Spectrum of DHCR7 Pathogenic Variants in Representative Czech and Hungarian Population Cohorts.
Smith-Lemli-Opitz syndrome (SLOS) is an inborn error of cholesterol biosynthesis, caused by biallelic mutations in the DHCR7 gene. Genotype-phenotype correlations regarding DHCR7 variants could explain the variation in severity, ranging from in utero demise or severe SLOS to a mild phenotype. Clinical recognition can be challenging. This study aimed to determine the frequency of SLOS carriers in the Central European population, as well as the mutational spectrum of DHCR7 in these carriers. A retrospective analysis of DHCR7 variants was conducted using next-generation sequencing data from 55,289 individuals in Czech and Hungarian genetic laboratories. The SLOS carrier frequency and the mutational spectrum of the DHCR7 gene in its carriers were established in the Czech and Hungarian sub-cohorts. In the combined dataset, we identified causative DHCR7 variants on 1567 alleles among 55,289 tested individuals, contributing to an SLOS carrier frequency of 2.83%. Of the 31 DHCR7 variants detected, the c.452G>A variant was the most prevalent, accounting for 1.8% of all detected alleles in our cohorts. In contrast, the c.964-1G>C variant was more frequent in non-Finnish Europeans, as indicated by the gnomAD 4.1.0 database. The DHCR7 mutational spectra of patients and carriers were comparable in terms of the most common variants. The high SLOS carrier frequency (2.83%) underscores the importance of SLOS carrier screening in Central European populations. The prevalent DHCR7 null mutations and their potential combinations may explain the lower-than-expected prevalence of SLOS, whilst Central and Eastern European populations remain likely underrepresented in the current gnomAD database.
Unveiling a New Link: Cholesterol Deficiency in Smith-Lemli-Opitz and Niemann-Pick C as a Driver of Ciliopathies.
The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia-associated proteins. Recently, it has become apparent that the composition of the ciliary membrane influences its function. For instance, the ciliary membrane contains more cholesterol than other regions of the cell membrane and a variety of unique receptors and ion channels. Additionally, it appears that primary cilia have evolved to lower the threshold for activating signal transduction by establishing the environment essential for signaling pathways on a limited portion of the cell surface. By positioning receptors and downstream signaling components in this thin protrusion at a precise time and location within the plasma membrane, the cell can better orient its physiological response to external stimuli. Cholesterol deficiency can alter cilia formation and function with effects on Sonic hedgehog signaling. In this review, we discuss these new concepts and apply them to the developmental disorder Smith-Lemli-Opitz syndrome and the developmental and neurodegenerative disorder Niemann-Pick C disease, demonstrating that they are also ciliopathies.
Temporal transcriptomic changes during neurodevelopment in a mouse model of Smith-Lemli-Opitz syndrome.
Smith-Lemli-Opitz syndrome (SLOS) is a cholesterol biosynthesis disorder caused by mutations in the DHCR7 gene, leading to reduced cholesterol production and accumulation of its precursor, 7-dehydrocholesterol. SLOS displays a wide range of neurodevelopmental defects, intellectual disability, and behavioral problems. However, an in-depth study of the temporal changes in gene expression in developing brains has not been conducted before. In this work, we carried out the transcriptomic analysis of whole brains from WT and Dhcr7-KO mice at embryonic day 12.5 (E12.5), E14.5, E16.5, and postnatal day 0 (PND0). First, we observed the expected downregulation of the Dhcr7 gene in the Dhcr7-KO brains, as well as changes in other genes involved in cholesterol biosynthesis at all time points. Pathway and GO term enrichment analyses revealed affected signaling pathways and biological processes that were shared amongst time points and unique to individual time points. Specifically, pathways important for embryonic and neural development, including Hippo, Wnt, and TGF-β signaling pathways, are most significantly affected at the earliest time point, E12.5. Additionally, neurogenesis-related GO terms were enriched at earlier time points, consistent with the timing of development. Conversely, pathways related to synaptogenesis, which occur later in development than neurogenesis, are significantly affected at the later time points, E16.5 and PND0, including cholinergic, glutamatergic, and GABAergic synapses. In vitro neurogenesis experiments using GABAergic neuronal precursors isolated from embryonic mouse brain confirmed that loss of Dhcr7 led to decreased proliferation and premature neurogenesis, consistent with the transcriptomic changes.
