Pedigrees of the four Jordanian families participating in the study. Squares, circles, and dashes represent males, females, and deceased individuals, respectively. Arrows indicate probands. Solid symbols refer to affected individuals and open symbols to normal or carrier individuals. The two dashed squares in family F1 pedigree divide it into F2‐A and F2‐B. Double horizontal lines indicate consanguinity. M/M, homozygous mutated; M/W, heterozygous mutated; W/W, homozygous wild type. Zygosity for individuals III‐2 and III‐3 in family F1‐A is written in two lines, the above one for CLRN1 (c.433+1G>A), and the lower one for ABCA4 (c.5460+1G>A)
