Genomic analysis revealed an individual mutation in MTMR2 gene. The genealogy of the family and the MTMR2 electropherograms show the same novel homozygous c.1490dupC; p.Phe498IlefsTer2 mutation identified in all three siblings in family 1 (A) and a homozygous c.1479+1G>A splice site mutation in family 2 (B) and in family 3 (C) a homozygous c.1090C>T; p.Arg364Ter stop mutation and in family 4 (D) a homozygous c.883C>T; p.Arg295Ter mutation in the MTMR2 gene was revealed. Parents were heterozygous for the same mutation as their children in all three families.
