Article Synopsis
- * A pilot screening program in Russia analyzed 202,908 newborns, finding 157 with trisomy 21, indicating a birth prevalence of 1:1,284, and explored their lymphocyte levels (TREC and KREC).
- * Results showed reduced TREC values in DS newborns, similar to extremely preterm infants, and significant KREC differences from the general newborn population, highlighting the need for deeper research into immune development in DS and better support from healthcare teams.
Background: This study presents the findings of a newborn screening (NBS) pilot project for 5q-spinal muscular atrophy (5q-SMA) in multiple regions across Russia for during the year 2022. The aim was to assess the feasibility and reproducibility of NBS for SMA5q in diverse populations and estimate the real prevalence of 5q-SMA in Russia as well as the distribution of patients with different number of SMN2 copies.
Methods: The pilot project of NBS here was based on data, involving the analysis of 202,908 newborns.
Newborn screening (NBS) for severe inborn errors of immunity (IEI), affecting T lymphocytes, and implementing measurements of T cell receptor excision circles (TREC) has been shown to be effective in early diagnosis and improved prognosis of patients with these genetic disorders. Few studies conducted on smaller groups of newborns report results of NBS that also include measurement of kappa-deleting recombination excision circles (KREC) for IEI affecting B lymphocytes. A pilot NBS study utilizing TREC/KREC detection was conducted on 202,908 infants born in 8 regions of Russia over a 14-month period.
