A novel recessive splicing mutation in the POU1F1 gene causing combined pituitary hormone deficiency.

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
backgroundMutations in the gene encoding the pituitary transcription factor POU1F1 (Pit-1, pituitary transcription factor-1) have been described in combined pituitary hormone deficiency (CPHD).
aimThe aim of this study was the characterisation of the molecular defect causing CPHD in a patient born to consanguineous parents. SUBJECT AND
methodsThe case of a 12.5-yr-old girl presenting with severe growth failure at diagnosis (-3 SD score at 3 months) and deficiency of GH, PRL, and TSH was investigated for the presence of POU1F1 gene mutations by denaturing high performance liquid chromatography analysis.
resultsA novel mutation adjacent to the IVS2 splicing acceptor site (IVS2-3insA) was identified in the patient at the homozygous state. Analysis of patient's lymphocyte mRNA and an in vitro splicing assay revealed the presence of 2 aberrant splicing products: a) deletion of the first 71 nucleotides of exon 3, altering the open reading frame and generating a premature stop codon, b) total exon 3 skipping resulting in an in frame deleted mRNA encoding a putative protein lacking part of the transactivation domain and of the POUspecific homeodomain. Notably, the patient's relatives heterozygous for the mutation had PRL levels under the normal range with no evident clinical symptoms.
conclusionsThe IVS2- 3insAmutation, responsible for CPHD at the homozygous state, causes the presence of 2 aberrant splicing products encoding non-functional products. In the heterozygotes one normal allele might not guarantee a complete pituitary function.
