Figure 1. Mutations in the FERM domain containing 7 gene identified in four families with congenital motor nystagmus

Mutations in FRMD7 identified in four families with CMN (A, B, C, and D). Each column from left to right represents pedigree of each family, mutant FRMD7 sequence, and corresponding normal sequence. The exact mutation was labeled under each sequence according to the nomenclature recommended by HGVS. Arrow indicates the proband in each family.
