Figure 2. Identification of LEPRE1 mutations.

Figure 2

A: A partial sequence of PCR product of Patient II-3 is shown. Compound heterozygous frame shift mutations (c.484delG, p.A162LfsX22 and c.2155dupC, p.E719RfsX11) are indicated by arrows. The mutations have been confirmed by the subsequent sequencing of subcloned products of normal and mutant alleles. B: Schematic presentation of the positions of the mutation. LEPRE1 cDNA encodes the tetratricopeptide repeat domain (four black regions), the Prolyl/Lysyl/hydroxylase domain (green region), and the KDEL ER- retrieval motif (red region). LEPRE1 with a p.E719RfsX11 change results in the lack of only the KDEL ER-retrieval sequence, whereas other functional domains remain intact.
