The L0d1,2 branch was separated from their ancestral node by two mutations, 498delC and a back-mutation, 16278C!
There was a perfect match to the Y chromosome of a Moroccan Jew, and matches that differed by two mutations from another Moroccan Jew, a Kurdish Jew and an Egyptian.
Adult-onset SMA followed by cardiac involvement is a dominant disorder caused by two mutations in prelamin-A/C (LMNA) (Rudnik-Schöneborn et al., 2007).
The rol-3 locus was originally defined by two mutations, e202 and e754 (Brenner, 1974), both of which give rise to an adult specific left-hand roller (LRol) phenotype.
The adaptation was acquired by two mutations which increased binding (VP1 T125K) and replication (3A E41K), respectively.
A polyadenylation signal (AATAAA) can be created at position 94 of forward strand of PRAT consensus sequence by single point mutation, as well as at position 50 of the reverse strand by two mutations.
The E-M35* undifferentiated state of two Jews and one Amhara from Ethiopia previously reported [8] has now been resolved by two mutations (V42 and V92, respectively), that identify two additional clades within the E-M35 haplogroup.
The amino acid sequence of SHV-31 differs from SHV-1 by two mutations, namely, L35Q and E240K, and differs from SHV-12 by one mutation (G134S).
In summary, the functioning of bridge mt-B2c could be compromised by two mutations found in human 12S rRNA, 450G>A (m.1097G>A) and 507A>C (m.1154A>C) (33, 38).
Dioecy likely evolves from hermaphrodite or monoecious ancestors by two mutations with the first causing male sterility and the second reducing female fertility.
