Fine-mapping of ZDHHC2 identifies risk variants for schizophrenia in the Han Chinese population.
Article in Molecular genetics & genomic medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundZDHHC2 is a member of the DHHC protein family, mediating palmitoylation of postsynaptic density-95 (PSD-95) and A-kinase-anchoring protein 79/150 (AKAP79/150). Genome-wide association studies (GWASs) have identified ZDHHC2 as a candidate gene for schizophrenia (SCZ). We aimed to fine-map variants of ZDHHC2 conferring risk to SCZ in the Han Chinese population.
methodsTargeted sequencing of whole-exome sequences including untranslated regions (UTRs) along with neighboring regions in 1,827 schizophrenic patients and 1,004 normal controls of Han Chinese origin.
resultsA total of 123 variants, including five common and 118 rare variants, were identified. Among common variants, rs73198534, rs530313445, and rs74406481 were significantly associated with SCZ. Nine nonsynonymous rare variants, p.Glu96fs, p.Arg127X, p.Val145Ile, p.Ala177Thr, p.Arg269Gln, p.Asn312His, p.Glu319Lys, p.Gln340X, and p.Ile347Val, identified only in patients; eight are located in the important domains, including two stop-gain variants. The 3D structural analysis and functional prediction revealed that all these eight variants may affect AMPAR expression or function, and influence the synaptic plasticity by regulating the palmitoylation of PSD95 and AKAP79/150.
conclusionOur results first show strong supportive evidences of the association between the ZDHHC2 and SCZ, and also provide a fine-mapping of variants of this gene in Han Chinese SCZ patients.
