New variants and genotype–phenotype correlation in KIF5A mutation: the contribution of a large Italian cohort

This study investigates changes in the KIF5A gene, which plays a key role in moving materials within nerve cells. Mutations in this gene can lead to neurological diseases like hereditary spastic paraplegia (HSP), Charcot-Marie-Tooth disease (CMT2), and amyotrophic lateral sclerosis (ALS). By analyzing 390 Italian patients, the researchers found five individuals with harmful KIF5A mutations. […]

Shprintzen-Goldberg syndrome: follow-up of the cardiovascular features in an international cohort of 29 patients with SGS

This study sheds new light on the long-term heart issues linked to Shprintzen-Goldberg syndrome (SGS), a rare connective tissue disorder in the same family as Marfan syndrome. Unlike previous literature with limited data, this analysis of 29 international patients reveals that nearly half develop mitral regurgitation, and over a third experience thoracic aortic aneurysms. Importantly, […]

Reproductive decision-making and pregnancy in germline CDH1 variant carriers

Diffuse gastric and lobular breast cancer (DGLBC) syndrome is an autosomal dominant disorder linked to pathogenic variants in the CDH1 gene. We performed a survey-based analysis of reproductive decision-making in 121 individuals with CDH1 variants, including 6 women who gave birth after prophylactic total gastrectomy (PTG). Approximately half of individuals reported that their CDH1 diagnosis […]

Integration of genetic counselling into a multidisciplinary urological oncology programme enhances access and detection of hereditary prostate cancer syndromes

Hereditary genetic testing can play a vital role in identifying cancer risks and informing care for individuals with prostate cancer and their families. This study evaluated the impact of integrating a dedicated genetic counselor into a multidisciplinary prostate cancer clinic. Following this change, referrals for genetic counseling and completion of genetic testing rose significantly. More […]

The γ-Actin with pathogenic variants of sites on actin-binding proteins caused earlier onset and more malignant progressive hearing loss

DFNA20/26-related hearing loss shows considerable variability in both severity and age of onset. In this study, the authors discovered a new ACTG1 variant (p.Ile327Met) of DFNA20/26 and found that its location in a protein-binding region of the γ-actin molecule leads to earlier and more severe hearing loss. These findings provide insight into how mutation sites […]

De novo heterozygous missense variants in ATP11A are associated with refractory focal epilepsy

The majority of focal epilepsy with unknown causes has genetic predisposition. This study demonstrates that de novo missense variants in ATP11A are associated with refractory focal epilepsy. Further systematic analysis indicates that variants located in transmembrane regions (TMs) are related to severe and multiple neurological symptoms, whereas non-TM variants are associated with mild and single […]

Disease burden by ALPL variant number in patients with non-life-threatening hypophosphatasia in the Global HPP Registry

Hypophosphatasia (HPP) is a rare disease caused by changes in the ALPL gene – these changes are also known as “variants”. This study analyzed 685 patients from the Global HPP Registry to compare disease burden in patients with 1 variant versus those with 2 or more variants in the ALPL gene. No differences were reported […]

A novel 8-octapeptide repeat insertion in PRNP causing Huntington disease-like 1 in a Chinese family: a case report and literature review

This study reports the first case of Huntington disease-like 1 (HDL-1) in a Chinese family, a rare genetic disorder caused by a mutation in the PRNP gene. The family presented symptoms resembling Huntington’s disease, including involuntary movements, cognitive decline, and mood changes, but genetic testing confirmed a unique 8-repeat insertion in PRNP. Notably, the patient’s […]

Novel founder variant in the S-antigen visual arrestin gene SAG is the most prevalent cause of autosomal dominant retinitis pigmentosa in Singaporean Chinese

A new study from Singapore identified a novel genetic variant in people of Southern Chinese heritage that causes a type of inherited vision loss termed retinitis pigmentosa (RP). This form of RP affects families across multiple generations. The change was found in numerous unrelated families but arose from a common ancestor. Because most Chinese people […]
