3 weeksSTATIM
3 daysCascade testing for GJB2 gene mutation (for Connexin 26) – early non-syndromic AR deafness

3 weeksSTATIM
3 daysDetection of deletions in genes associated with hearing impairment
Testing for STRC, OTOA, CATSPER2 gene duplication/deletion by Multiplex Ligation-dependent Probe Amplification (MLPA), responsible for hearing impairment: DFNB16, DFNB22.
Material:
Peripheral blood, Buccal swab …Turnover Time:
3 weeksSTATIM
3 daysHLA-C (C1/C2) Genotyping
HLA-C typing at the allelic resolution level is used for the detailed determination of HLA-C gene variants. This gene plays a crucial role in the communication between the mother's immune system and the developing embryo during pregnancy. HLA-C analysis helps identify specific combinations of maternal and fetal genes that may be associated with a higher risk of complications such as recurrent miscarriages, preeclampsia, intrauterine growth restriction (IUGR), or preterm birth. We recommend combining it with the KIR haplotype determination method.
