 COM  | 
Based on affected patient with maternal disomy associated with Robertsonian translocation (14;14) Pentao-1992 assigned the RMCH gene to Chr 14. Arbour-1997 did not find a linkage with Chr 14 markers and demonstrated that the disease gene lies within a 14cM interval which spans the Chr 2 centromere." |
