Fig. 2From: A role for VAX2 in correct retinal function revealed by a novel genomic deletion at 2p13.3 causing distal Renal Tubular Acidosis: case reportCharacterization and gene dosage of the genomic deletion at 2p13.3 (a) Successful PCR amplification across the junction breakpoint in the patient (P) and his parents (F, M) but not in a control individual with normal genomic DNA (C). b Sequencing revealed the insertion of 2 nucleotides (GG) at the site of the deletion. c Semi-quantitative PCR confirmed that gene dosage of ATP6V1B1 and exons 2 and 3 of VAX2 is reduced in the parents (F, M) compared to the control (C)Back to article page
