Overview
Brief Summary
The aim of the study is to obtain the initial experience of the inclusive genetic screening of newborn.
Two groups of newborns born in RCOGP will be enlisted to the study:
- newborns without developmental features having no variations according to an inherited diseases screening;
- newborns showing either phenotypic features or deviations according to MS screening.
The residual volume of the cord blood of all newborns form both groups will be collected and subjected to the whole exome sequencing. The sequencing data will be analyzed in "screening" mode for the first group while for the second group analysis will be performed taking the respective phenotype into account.
The study is planned to cover 7000 newborns in total.

Outcomes
Primary Outcomes
Phenotype-associated variants
Time Frame: 2 weeks - 2 months
Pathogenic, likely pathogenic variants or variants of uncertain significance corresponding to the observed clinical conditions
Motivations for refuse to participate
Time Frame: 1 day
Questionnaire answers provided by families refused to enroll
Estimate the frequency of revealing patients carrying genotype associated with a monogenic disese.
Time Frame: 3-5 months
The manifestation of pathogenic or likely pathogenic variants leading to a monogenic disease presenting during early age. A genotype is considered having risk of developping a monogenic disease in case pathogenic or probably pathogenic variants are detected corresponding to the inheritance model.
Acceptance of advanced screening
Time Frame: 1 day
Questionnaire answers provided by families accepted screening for variants of low penetrance, no care available etc.
Secondary Outcomes
- Oncological risk(1 day)
- Cardiological risk(1 day)
- Recessive carriers(1 day)
