OBJECTIVES

2. Proteomics expression of Vit D deficiency

1. Identify genetic mechanism of Vit D defiency

CASE STUDY: VITAMIN D & CALCIUM

Step 5: Check X levels in lab results, questionnaires, EMR - HM

get baseline characteristics

Step3: Check SNPs in the protein statistically diff - RZ

identify impact status

Moderate

affecting effectiveness

High

affects prot structure

Step2: Perform proteomics diff expression - RZ

Step1: Categorize groups - HM

WORKFLOW 2: From 14k, we segregate samples into

previous work by others

3 dominant gene variants

~1223 samples

>12ng/ml, < 20 ng/ml

normal/sufficient

~1049 samples

>=20 ng/ml

~576 samples

how many of these 4205 samples have proteomics data

get the genetic variants profile

filter proteomics using "HDL associated proteins" ~ 100 types

low APO-X

high APO-X

proteomics expression analysis

find statistically sig protein expression

compared genetics w protein exp

HIGH

match w n=270

compare the proteins

Subtopic

genetic variants that causes X to the proteins in previous studies

<12 ng/ml

WORKFLOW 1: get list of proteins enriched in vitD deficiency from our proteomics study (n=270)

find the genetic variants associated w them

indirect

non-coding region

coding but modifier

it regulates the expression of the protein

direct

coding region

moderate impact

it reduces the effectiveness of a protein

high impact

it affects protein structure formation

certain genes linking vitD defeciency with

some ppl have higher rate of deciciency compared to others

this means there might be genetic/inherited factors
