Variation concise descriptions

Human-readable summaries of alleles that include a description of its lesion, its effect on the gene's function, and resulting phenotypes. These descriptions aim to recreate summaries like those in the C. elegans I & II books and enhance them with up to date data. A first step is to make and display summaries for each variation; second step is to extract info and combine the summaries of a gene's variations and display them on the corresponding gene pages.

From C. elegans II
e51 : paralysed kinky small irregular pharyngeal pumping able to lay eggs. ES3 ME0. NA > 30
(e450amber e312amber (non-null) e309 (see sup- 6) etc.; all similar to e51 or slightly weaker).
See also e51, e328, e450, e973, e985, e2208, e2274 [C.elegansII] e51 : paralysed, kinky, small,
irregular pharyngeal pumping; able to lay eggs. Ric, high acetylcholine levels; variable
neuroanatomical defects.ES3 ME0. OA>30: e450amb, e312amb (non-null),e309 (suppressed by
sup-6), s69, s178 etc. All alleles similar to e51 or slightly weaker.

MGI produces these summaries (do not know if they are automated): for MGI:95294

Mutations widely affect epithelial development. Null homozygote survival is strain dependent, with
defects observed in skin, eye, brain, viscera, palate, tongue and other tisses. Other  mutations
produce an open eyed, curly whisker phenotype, while a dominant hypermorph yields a thickened
epidermis.

Sample allele summaries:

ju2 is a null allele of syd-1(F32D2.5). The ju2 lesion is a nonsense point mutation that results in a
truncation of all 3 SYD-1 isoforms. ju2 results in defects in axodendritic polarity of ASI and L1 DDs,
neuron morphology of ASI but not DD or VD neurons, presynaptic component localization, synaptic
remodeling of VDs in adults, and backward movement resulting in coiling. ju2 animals do not show
defects in neurite development or postsynaptic component localization.
e1368 is a reduction-of-function/hypomorphic allele of the insulin/IGF receptor ortholog daf-2. The
e1368 lesion is a missense mutation affecting 5 of 6 coding transcripts daf-2. e1368 affects many, but
not all DAF-2-activity requiring processes. Specifically, e1368 disrupts DAF-2 processes of embryonic
and larval development, formation of the developmentally arrested dauer larval stage (diapause),
adult longevity, fat storage, salt chemotaxis learning, and stress resistance, including response to
high temperature. e1368 mutants are temperature sensitive and are dauer constitutive at 22.5 deg. In
addition, e1368 animals have extended life spans. e1368 animals do not show any defects in acetylcholine
esterase activity, carbon dioxide avoidance, diacetyl chemotaxis, and DMPP response.

problems
  • coding vs noncoding genes
  • mutation in noncoding area of gene
  • mutation affects isoforms differently
  • only use variations mapped onto human proteins, rather than other way around - keep in sync with with other projects, also limits sentence to a subset of isoforms?
  • ..."that is or is not conserved in humans." can only use under limited situations, orthology needs to be done.

Rules for Process sentence construction

  • Rule 1: Ignore all lines that do no have "IMP" in column 7
  • Rule 2: Map column 8 WBVariation to <allele public name> -
*use obo_name_variation.pg at tazendra /home/postgres/work/pgpopulation/obo_oa_ontologies/geneace
*WBVarID is in first column of geneace file, public_name is second column of geneace file
  • Rule 3: When there are more than one WBVarIDs in column 8, map other WBVarIDs and create a separate summary for those objects
  • Rule 4: Map column 5 GO:ID to GO name -
*use obo_goidprocess at tazendra /home/postgres/work/pgpopulation/obo_oa_ontologies

obo_goidprocess looks like:

GO:ID in line id: <GO:ID#######>
name in line name: <GO name>
If GO:term name starts with a qualifiers "negative" or "positive", replace qualifier with "the"

Example:
js901 affects unc-104 function in anterograde synaptic vesicle transport. Based on column 8 WBVar02141295 ->js901, column 3 unc-104, column 5 GO:00048490
js415 affects sam-4 function in the regulation of anterograde synaptic vesicle transport. Based on column 8 WBVar02125688 -> js415, column 3 sam-4, column 5 GO:1903744 -> positive regulation of anterograde synaptic vesicle transport -> Replace "positive" with "the" -> the regulation of anterograde synaptic vesicle transport

  • Rule 5: Italicize <variation> public name and column 3 gene
  • Rule 6: If there are two variations listed in column 8, make a summary for each variation each using the GO value in column 5 of the line
  • Rule 7: If the genes and alleles are the same in each line, concatenate GO:IDs, comma separate or join with “and”
*Example: 
 *nj21 affects maco-1 function in chemotaxis and neuronal signal transduction
 *nj34 affects maco-1 function in chemotaxis and neuronal signal transduction

title : Sequential action of Caenorhabditis elegans Rab GTPases regulates phagolysosome formation during apoptotic cell degradation.
Sequencing of rab-14 in qx18 mutants revealed a C to T transition, which resulted in substitution of the Threonine at codon 67 with Methionine (ACG > ATG; T67M). This mutation affects the phosphate/Mg2+
binding domain PM3, which is conserved in all members of the Ras GTPase superfamily

Sentences to make: 
*Molecular sentence 2: "qx18 encodes a C to T transition, T67M which affects the phosphate/Mg2+ binding domain PM3" 
*Orthology sentence: "The phosphate/Mg2+ binding domain PM3 is conserved in all members of the Ras GTPase superfamily"

SECTION: results. This allele encodes a mutation where glycine 169 in the BH3 binding pocket is replaced with glutamate ( Fig . 4C ) ( Hengartner and Horvitz , 1994a ) , which inhibits EGL-1 from binding and triggering a conformational change in CED-9 ( del Peso et al . , 2000 ; Yan et al . , 2004 )
SECTION: results. In the gain-of-function ced-9 ( n1950sd ) allele , glycine 169 , which resides in the CED-9 BH3 binding pocket , is mutated to glutamate ( G169E ) . [Field: results, subscore: 3.00]
SECTION: results. To test whether co-expression of DRP-1 modulates CED-9 via interactions with the BH3 binding pocket , we first created a construct corresponding to the ced- 9 ( n1950gf ) allele .

Sentence to make: 
*Molecular sentence 2: "n1950 encodes a G169E change in the BH3 binding pocket of CED-9"

“the sy262 mutation lies within the Rac GEF Dbl domain , it is possible that the mutation acts through one or both of the GTPases .”
“In conjunction with molecular modeling , our data suggest that the C . elegans mutation as well as an equivalent mutation in human SOS1 activate the MAPK pathway by disrupting an auto-inhibitory function of the Dbl domain on Ras activation “
“A mutation equivalent to sy262 G322R activates hSOS1.”
“...in every experiment we found that at some time point, hSOS1 C282R dis- played two- to fourfold more activity than wild-type hSOS1. In conjunction with our genetic data, these data suggest that the G322R change in C. elegans SOS-1, as well as the equivalent C282R change in hSOS1, does indeed enhance EGF-dependent MAPK activation.”

Sentence to make: 
*Molecular sentence 2: "sy262 encodes a G33R mutation in the Rac GEF Dbl domain and is equivalent to a C282R change in the human hSOS1."
*Orthology sentence: "The sy262 G33R mutation is equivalent to a C282R change in the human hSOS1."

results. The region surrounding the conserved valine ( bold ) that is mutated to a glutamate in the ad1302 allele ( resulting from a T to A mutation in the second base of the V60 codon ) is shown lined up with the corresponding region in other GluCl subunits and in the rat glycine and -aminobutyric acid ( GABA ) type A- channel subunits ( 29 , 30 ) . [Field: results]

Sentence to make: 
*Molecular sentence 2: "ad1302 encodes a Val to Glu change."
*Orthology sentence: "ad1302 affects a region that is conserved in GluCl subunits as well as in rat glycine and GABA type A-channel subunits."

SECTION: abstract. The pop-1 ( q624 ) allele is weakly penetrant for multiple defects and appears to be a partial loss-of-function mutation ; pop-1 ( q624 ) alters a conserved amino acid in the HMG-box DNA binding domain . [Field: abstract]
SECTION: discussion. This mutation alters a conserved amino acid in the HMG box DNA binding domain which is conserved specifically in TCF / LEF- 1 type HMG proteins ( Laudet et al . , 1993 ) , suggesting that the pop-1 ( q624 ) mutation may affect either recognition of the TCF / LEF-1 consensus sequence or DNA binding affinity , thereby lowering POP-1 activity . [Field: discussion]
SECTION: discussion. As the only mutation isolated thus far in a developmental system that changes a highly conserved amino acid in the -catenin binding domain , the pop-1 ( q645 ) missense mutation may shed new light on TCF / LEF-1 function during development . [Field: discussion]
SECTION: introduction. The pop-1 ( q624 ) allele is weakly penetrant for multiple defects and appears to be a partial loss-of function mutation ; pop-1 ( q624 ) alters a conserved amino acid in the HMG-box DNA binding domain . [Field: introduction]
SECTION: results. The pop-1 ( q645 ) mutation carries a nucleotide substitution predicted to change an aspartic acid ( D ) to a glutamic acid ( E ) ( Fig . 2B ) ; this mutation resides within the pop-1 -catenin binding domain and alters an amino acid conserved in all known TCF / LEF-1 proteins , including nematode , fly , and vertebrate homologues . [Field: results]
SECTION: results. The pop-1 ( q624 ) mutation possesses a nucleotide change in the region encoding the HMG box ; the predicted amino acid change in this case also affects a conserved amino acid ( Fig . 2C ) . [Field: results]

Sentence to make: 
*Molecular sentence 2: "q624 encodes a D to E change in the catenin binding domain" 
*Orthology sentence: "q624 affects a conserved amino acid in the HMG-box DNA binding domain specifically in TCF/LEF-1 type HMG proteins"
