Topic: pedigree tree creation
Jayashree Surnar (Jul 06 2017 at 05:58):
hello all, any ideas how to implement the pedigree tree creation.
Thank you.

Have you looked at the genetic family history profile?
Jayashree Surnar (Jul 06 2017 at 08:50):
tnq @Lloyd McKenzie. Yep, few min back i have gone throug that profile.
Lloyd McKenzie (Jul 06 2017 at 08:53):
Does it answer your question?
Jayashree Surnar (Jul 06 2017 at 08:55):
in the specification given, FamilyMemberHistory is one of the event resources in the FHIR workflow specification.Here
my doubt is to create this which one we need to choose among operation,messaging,workflow?
any suggetion?
Jayashree Surnar (Jul 06 2017 at 12:40):
i didn't understand the extension family-member-history-genetics-parent, family-member-history-genetics-sibling,family-member-history-genetics-observation . means by using this profile how to create the Pedegree tree
Lloyd McKenzie (Jul 06 2017 at 15:32):
Did you look at the example?
Jayashree Surnar (Jul 07 2017 at 04:30):
if we look at this extension http://build.fhir.org/extension-family-member-history-genetics-parent.html , this is used on FamilyMemberHistory. Capture.PNG and in the extension again it's refering to FamilyMemberHistory. would you please give one example, i'm not understanding the realtime scenario
Jayashree Surnar (Jul 07 2017 at 04:37):
actually we have familymember relation to the patient in the FamilyMemberHistory resource it self right, then again whats the use of these extensions?using this profile(FamilyMemberHistory-genetic) how to impl the UI ? i'm confused.

@Lloyd McKenzie , i'm littlebit confusing with the examples given in the FamilyMemberHistory. (the relationship references given)
ex http://build.fhir.org/list-example-familyhistory-genetics-profile.json.html
could you plz explain this example:
{
"resourceType": "FamilyMemberHistory",
"id": "4",
"extension": [
{
"url": "http://hl7.org/fhir/StructureDefinition/family-member-history-genetics-sibling",
"extension": [
{

"valueCodeableConcept": {
"coding": [
{
"system": "http://hl7.org/fhir/v3/RoleCode",

}
],
"text": "natural sister"
}
},
{
"url": "reference",
"valueReference": {
"reference": "FamilyMemberHistory/mother",
"display": "paternal grandmother"
}
}
]
}
],
"status": "completed",
"patient": {
"reference": "Patient/example",
"display": "Pam Taylor"
},
"name": "Alica",

}
},

i understand the diff b/w FamilyMemberHistory Resource and FamilyMemberHistory-Genetic profile. but confusing with the relationship references.
what i understand is:
Family MemberHistory only describes “a relationship of a family member to a patient” where as the
FamilyMemberHistory-Genetic profile describes the relative relationship too. .e using the extension
--> http://build.fhir.org/extension-family-member-history-genetics-parent.xml.html(Identifies a parent of the relative)
--> http://build.fhir.org/extension-family-member-history-genetics-sibling.xml.html(Identifies a sibling of the relative)
but again in the extension there is a reference to FMH .i'm confusing at this point. so please help.
Lloyd McKenzie (Jul 07 2017 at 15:03):
The extensions let you fully define a family tree. If you have a maternal cousin, that doesn't tell you which maternal aunt or uncle they were born of, nor does it tell you whether it's the aunt or the uncle that's a child of your grandparents. By using the extension, you can indicate the mother and father of each relative and thus build the full family tree. You can also indicate "twin" relationships as there can be additional biological relevance there.
Lloyd McKenzie (Jul 07 2017 at 15:05):
If you just have the base FamilyMemberHistory resource without the extensions, you can't draw a full family tree once you get beyond immediate relatives. And if you get into step-siblings, you can't even draw it for immediate family
Jayashree Surnar (Jul 10 2017 at 04:15):
tnq @Lloyd McKenzie , i understand the scenario, but still i a have doubt,
for example i'm using the extension http://build.fhir.org/extension-family-member-history-genetics-parent.xml.html here the relationship we are talking is b/w the patient's relative and his/her parent, and in the extension we have to give reference to the FMH which is relative's parent family member history or the relative's FMH itself?
Lloyd McKenzie (Jul 10 2017 at 14:59):
All of the FamilyMemberHistory instances in the tree would have the same "patient". There's an extension that lets you link a FamilyMemberHistory record to the corresponding Patient of that family member's record, but that's not often done because of the privacy implication of linking patients' medical records.
Jayashree Surnar (Jul 11 2017 at 04:45):
okay @Lloyd McKenzie .
Tnq.
Jayashree Surnar (Jul 11 2017 at 12:56):
if we have patient's Father,mother,sis/brother then no need of extensions as those are directly related to patient AND if we have patient's uncle then we need the extensions. i'm i correct?
Lloyd McKenzie (Jul 11 2017 at 15:08):
If you have the patient's natural mother, father and differentiate natural brother/sister from step brother/sister, then yes. But as soon as there's step-parents, step-siblings, adoptive parents, etc. you're going to need the relationships
