Novel TECPR2 variant in two cases of hereditary sensory and autonomic neuropathy type 9: insights from genetic characterization and comprehensive literature review.
Review in BMC neurology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHereditary sensory and autonomic neuropathy type 9 (HSAN9) is a rare genetic disorder caused by genetic alterations in the TECPR2 locus and is characterized by developmental and intellectual disability, respiratory dysfunction, gastroesophageal reflux disease (GERD), and sensory and autonomic dysfunction, which are shared among the HSAN family.
methodsWhole-exome sequencing (WES) was performed on samples from both probands, and the relevant genetic variants were confirmed in their families using Sanger sequencing. Additionally, a comprehensive literature review was conducted on previously reported cases of HSAN9, and the clinical and genetic data were assessed to provide insight into the genetic and clinical characteristics of the disease.
resultsWe identified two new cases of HSAN9 with a shared novel variant of TECPR2 (NM_014844.5), c.1568del: p.Ser523PhefsTer12, classified as pathogenic according to ACMG guidelines. The probands showed characteristics of GERD, respiratory dysfunction, gait abnormalities, and developmental and speech delay, and both cases were deceased as a result of severe respiratory infection. The results of the literature review included 34 cases from 9 studies, revealing a wide range of genetic and clinical characteristics.
conclusionsOur study identified two new cases of HSAN9 with a novel variant in TECPR2, confirmed by WES. The clinical characteristics of the patients as well as the conduction of a comprehensive literature review are crucial in the early diagnosis and management of the disease and establishment of genotype-phenotype correlations.
