A case of carbonic anhydrase type VA deficiency presenting as West syndrome in an infant with a novel mutation in the CA-VA gene.
Article in Epilepsy & behavior reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Carbonic anhydrase VA (CA-VA) deficiency is a rare autosomal-recessive inborn error of metabolism. It is imperative to consider CA-VA deficiency as a differential diagnosis in neonates with hyperammonemia not attributed to defects in urea cycle enzymes, organic acid disorders, hypoglycemia, and primary hyperlactatemia. The case described in this report had a metabolic crisis on day three of life with biochemical abnormalities demonstrating hypoglycemia, elevated ammonia, and lactate. At eight months, he presented with developmental delay and infantile spasms. Considering the history of consanguinity and infantile spasms, clinical exome sequencing was done, which revealed a pathogenic novel mutation suggestive of CA-VA deficiency. On review of the literature, we found that about 21 affected individuals have been reported to date. Unprovoked seizures or epilepsy have not yet been described in CA-VA deficiency. This report expands the phenotypic spectrum of neurological manifestations of CA-VA deficiency and adds to the existing number of cases in the reported literature.
