We successfully treated a patient with homozygous familial hypercholesterolemia (HoFH) with stable coronary arterial disease using optimal medical therapy and low-density lipoprotein (LDL) apheresis for 16 years without percutaneous coronary intervention or bypass surgery. Intensive LDL lowering using apheresis and medication protected the patient from coronary atherosclerotic progression even in HoFH.

There are hundreds of rare syndromic diseases involving hearing loss, many of which are not targeted for clinical genetic testing. We systematically explored the genetic causes of undiagnosed syndromic hearing loss using a combination of whole exome sequencing (WES) and a phenotype similarity search system called PubCaseFinder. Fifty-five families with syndromic hearing loss of unknown cause were analyzed using WES after prescreening of several deafness genes depending on patient clinical features.

Objective: The objective of this study was to rigorously investigate and elucidate the genetic mechanisms underlying the formation of the RH blood group in a specific case and to systematically analyse the RH blood group genes among the family members of the proband.
Methods: Serological methods were used to determine the RH blood group phenotype of the proband. To elucidate the underlying genetic mechanism responsible for the RH phenotype, a comprehensive approach was undertaken, including RHCE genotyping, sequencing of RHD and RHCE genes, and exon sequencing of RHAG.

Purpose Of Review: Homozygous familial hypercholesterolaemia (HoFH) is characterized by marked elevation of low-density lipoprotein cholesterol (LDLC) and premature atherosclerotic cardiovascular disease. This is a review of novel pharmacological therapies to lower LDLC in patients with HoFH.
Recent Findings: Novel therapies can be broadly divided by whether their efficacy is dependent or independent of residual low-density lipoprotein receptor (LDLR) function.

Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) is an uncommon hereditary form of rickets characterised by chronic renal phosphate loss and impaired bone mineralisation. This results from compound heterozygous or homozygous pathogenic variants in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), a key producer of extracellular inorganic pyrophosphate (PPi) and an inhibitor of fibroblast growth factor23 (FGF23). ENPP1 deficiency impacts FGF23 and increases its activity.

Background: Multiple AD risk genes are implicated in lipid metabolism, and plasma and brain lipid levels are altered in AD. Astrocytes are enriched in key lipid-related factors and are likely contributors to altered lipid homeostasis in AD. We hypothesize that APP/Aβ-related pathology and neuroimmune factors modulate astrocytic gene transcription that promote maladaptive changes in lipid pathways, including aberrant astrocytic production and release of lipids that could affect Aβ pathology and neuronal deficits.
