Subject: [DNA] FTDNA admits to errors in many mtDNA sequences
Date: Thu, 4 Feb 2010 08:00:08 -0000


List

Last autumn FTDNA realised that the string of mutations '524.1C, 524.2A, etc.'
that started to appear in its mtDNA sequences in 2007 are all erroneous.
But the extent of the problem has only now been appreciated

The mutations string should always be '523.1C, 523.2A, etc.'.
We have now been told that the error was due to a software fault
- and affected hundreds, if not thousands, of results.

As I understand it, all the personal pages for mtDNA customers have now
been corrected, but customers have not been notified individually.

In respect of GenBank there are 38 affected sequences, with accession numbers:

EF363686 EF428259 EF452295 EF485042 EU089747 EU130551 EU135973
EU140898 EU156036 EU170361 EU232008 EU256375 EU330213 EU428753
EU564851 EU573192 EU616820 EU621708 EU677750 EU682394 EU682506
EU714298 EU715237 EU719115 EU746658 EU849002 EU855118 EU869314
EU926618 FJ194437 FJ449703 FJ490554 FJ605154 GQ149510 GQ200592
GQ281051 GQ891957 GU004259

I am very happy to provide any of the submitters of the above sequence with
a revised submission file (.sqn file) if they would like to get in touch with me.

This applies to all of the GenBank sequences and not just to the submissions
for which I prepared the original files.
