Hereditary neuropathy or pain disorder
Gene: TECPR2
The rating of this gene has been updated to Green and the mode of inheritance set to BIALLELIC, autosomal or pseudoautosomal following NHS Genomic Medicine Service approval.Created: 10 Oct 2023, 6:06 p.m. | Last Modified: 10 Oct 2023, 6:06 p.m.

Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Neuser et al. (2021) report 17 unrelated cases with a biallelic pathogenic variants in TECPR2. The study also includes 11 previously reported patients. The core manifestations in these individuals are global developmental delay/intellectual disability, muscular hypotonia, ataxia, hyporeflexia, respiratory infections, and central/nocturnal hypopnea. Peripheral neuropathy was present in two-thirds of all individuals. The majority of the pathogenic variants identified are truncating variants; however, missense variants were also found, predominantly located in the N-terminal and C-terminal regions. The TECPR2 gene is implicated in the autophagy pathway, which is critical to the development and function of the central nervous system. Loss of function variants in several genes of the autophagy pathway lead to both neurodevelopmental and neurodegenerative diseases. In summary, this gene should be promoted to GREEN in this panel, with autosomal recessive mode of inheritance.Created: 20 Jan 2023, 11:16 a.m. | Last Modified: 20 Jan 2023, 11:24 a.m.
