Identification of a frameshift deletion in <i>SLC29A3</i>.

<p>(A) Pedigree of the family. The <i>SLC29A3</i> genotypes of the patients and the family members from whom DNA was available for sequence analysis are listed under their symbols. Genotyping was carried out twice. (B) Illumina sequencing reads displayed for patient P1. Reads overlapping the mutation in exon 2 of <i>SLC29A3</i> (bp position g.73,082,741–g.73,082,765; hg19; NCBI 37) show the homozygous deletion of one A leading to a frameshift (c.243delA). (C) Diagram of <i>SLC29A3.</i> Introns are represented by a straight line. 5′-UTR and 3′-UTR are represented by open rectangles. The coding region is represented by closed rectangles. Previously reported mutations are indicated at the corresponding locations. The mutation identified in P1 and P2 is shown in a red rectangle. (D–E) Abnormal expression of <i>SLC29A3</i> transcript variants 1, 2 and 3 in the patients' EBV-B cells. (D) <i>SLC29A3</i> exons 2–4 were amplified from cDNA obtained from the EBV-B cells of two controls (Ctrl 1 and Ctrl 2) and two patients (P1 and P2) and were ligated to the pCR2.1 vector. Clones containing <i>SLC29A3</i> transcripts were sequenced, and the frequency of each variant was calculated by dividing the number of clones containing the particular transcript by the total number of sequenced clones. For Ctrl1: variants 1 and 2: 65/81 and variant 3: 16/81. For Ctrl2: variants 1 and 2: 37/44 and variant 3: 7/44. For P1: variants 1 and 2: 31/85 and variant 3: 54/85. For P2: variants 1 and 2: 20/76 and variant 3: 56/76. Each variant is represented by a diagram, with numbers indicating the number of the exon. The red vertical line indicates the position of the c.243delA mutation. The closed rectangle below each transcript variant represents the corresponding translation products. Gray boxes indicate amino acids modified with respect to the WT form. (E) Levels of <i>SLC29A3</i> mRNA (variants 1 and 3 combined) were assessed by Q-PCR on EBV-B cells from four healthy controls (Ctrls), two parents (Het.), and the two patients. Threshold cycles (Ct) for <i>SLC29A3</i>, normalized with respect to those of GUS (ΔCt), are plotted as 2^−(ΔCt). Each dot represents the mean of three independent experiments for each individual. The horizontal bars indicate the mean for all individuals sharing the same genotype.</p

Expression and characteristics of hENT3-variant3-81fs.

<p>(A) Scheme of hENT3-variant1-WT based on the protein structure predicted by SVMtm or TMpred programs. Transmembrane domains are represented by long rectangles. The gray and red boxes highlight the amino acids that are not identical in hENT3-variant1-WT and hENT3-variant3-81fs. In the gray box: amino acids 81–100 that are replaced by 20 other amino acids in hENT3-variant3-81fs. In the red box: amino acids 101–128 that are deleted in hENT3-variant3-81fs. (B) Levels of hENT3 proteins were assessed by immunoblotting with an anti-V5-tag antibody. The V5 tag was located at the C-terminus of hENT3. (C) The graph shows the relative <i>SLC29A3</i> mRNA levels measured by Q-PCR for the same experiment with the V5-tagged constructs. Threshold cycles (Ct) for SLC29A3, normalized with respect to those of GUS (ΔCt), are plotted as 2^−(ΔCt). Immunoblotting and Q-PCR results representative of three independent experiments are shown. (D) Adenosine transport activity. Uptake of [³H]adenosine (0.026 µM) in <i>Xenopus</i> oocytes 48 h after the injection of Δ36hENT3-variant1-WT or other variants with or without the 81fs mutation as well as one H (349fs) and one PHID syndrome (314fs) mutant cRNAs. pH-dependent uptake at pH 5.5. The data shown are the means ± SEM from three independent experiments. ^*, <i>p</i><0.05, ^***, <i>p</i><0.001.</p
