Klein, 2012 #915 Review

Parkin | PINK1 | DJ1

887 exonic mutations have been described to date, comprising 147 different changes.

  • About a third (293/887) of all exonic mutations are single-nucleotide changes,
  • 13% (119/887) are small deletions, and
  • 54% (475/887) are deletions or duplications of one or several exons (A Grunewald and C Klein, in prep.)

A deletion of exon 3 is the most frequent mutation in the Parkin gene (88/887, reported in 17 different studies). The second most common change is the c.924C>T (this is DNA level nomenclature, coding region, substitution) single-nucleotide mutation in exon 7 (RING1), which was detected 75 times in 13 different screens (A Grunewald and C Klein, in prep.).

Uncertain Spans

  • Portugal Table 1 rows 14, 36, and 37 are not clearly visible in this crop; rows visible enough to transcribe are retained and missing rows are not inferred.
  • Several long cDNA deletion strings in Portugal Table 1 are small and may contain punctuation or coordinate errors.
  • Klein 2012 review table is preserved as an image asset; only surrounding notes and highlighted aggregate statements are transcribed.
  • Darvish 2013 table gene labels at the far left are partly cropped; uncertain rows keep [uncertain] rather than inferred gene names.
  • The bottom transition into the following Results section is visible but not enough text is exposed to transcribe beyond the table region.
