Triggering receptor expressed on myeloid cells 2 (TREM2) homozygous mutations cause Nasu-Hakola disease, an early-onset recessive form of dementia preceded by bone cysts and fractures. The same type of mutations has recently been shown to cause frontotemporal dementia (FTD) without the presence of any bone phenotype. Here, we further confirm the association of TREM2 mutations with FTD-like phenotypes by reporting the first compound heterozygous mutation in a Turkish family.

Objective: To explore the genotypes and frequency distribution of thalassemia in Lingui District, Guilin City, and provide reference for the prevention and control of thalassemia in this area.
Methods: The results of genetic testing for thalassemia in 1 501 suspected cases at the Second Affiliated Hospital of Guilin Medical University were analyzed retrospectively. The deletional mutations of α-thalassemia were detected by gap-PCR, the non-deletional mutations of α-thalassemia and β-thalassemia mutations were detected by PCR-reverse dot blot (PCR-RDB).

The advancement of next-generation sequencing has spurred the growing adoption of whole-exome sequencing (WES) for genetic screening. Preimplantation genetic testing for monogenic disorders (PGT-M) can effectively prevent the transmission of pathogenic variants. However, interpreting vast data volumes and ensuring precise genetic counseling, especially with variants of uncertain significance (VUS), remains challenging.

Background And Objectives: POLR3-related disorders are a group of autosomal recessive neurodegenerative diseases that usually cause leukodystrophy and can lead to cognitive dysfunction. Literature reporting comprehensive neuropsychological assessment in POLR3A-related diseases is sparse. Here we describe the neuropsychological profile of a case of childhood-onset POLR3A-related spastic ataxia without leukodystrophy.

Background/aim: Autosomal-recessive carnitine-acylcarnitine translocase deficiency (CACTD) is a rare disorder of long-chain fatty acid oxidation caused by variants in the SLC25A20 gene. Under fasting conditions, most newborns with severe CACTD experience sudden cardiac arrest and hypotonia, often leading to premature death due to rapid disease progression. Understanding of genetic factors and pathogenic mechanisms in CACTD is essential for its diagnosis, treatment, and prevention.
