FIELD: biotechnology.
SUBSTANCE: invention relates to medical genetics and molecular biology and can be used for neonatal screening of 5q spinal muscular atrophy. Described is a process for detecting homozygous deletion of exon 7 of the SMN1 and SMN2 genes used for neonatal screening for 5q spinal muscular atrophy. It involves performing asymmetric PCR from blood stains on filter paper, followed by analysis of the melting curve of duplexes of complementary sequences of exon 7 of the SMN genes (SMN1 and SMN2) formed by hybridization probes of SEQ ID NO:3 and SEQ ID NO:4 and sequences of exon 7 of the gene and pseudogene.
EFFECT: performing neonatal screening using a process for detecting a homozygous deletion of SMN1 and SMN2 exon 7.
