Cryptic splice
WebSpinal muscular atrophy (SMA) is one of the major genetic disorders associated with infant mortality. More than 90% cases of SMA result from deletions or mutations of Survival Motor Neuron 1 (SMN1) gene. SMN2, a nearly identical copy of SMN1, does not compensate for the loss of SMN1 due to predominant skipping of exon 7. WebMay 25, 2024 · S5 Fig: A majority of cryptic 5’ SS activated under EJC-loss are weak.(A) Nucleotide content of cryptic 5’ SS.

WebApr 1, 2009 · In order to reliably distinguish authentic exons and splice sites from pseudo-exons and decoy splice sites, the splicing machinery must rely on auxiliary sequence features, such as intronic and exonic cis-elements. Among them, the Exonic Splicing Enhancers (ESEs) are the most studied.
WebDec 1, 2024 · Here, we describe a de novo cryptic splice site mutation in COL1A2 which results in a new splice acceptor site leading to deletion of 72 nucleotides (24 amino acids). This pathogenic, in-frame deletion, variant escaped detection by two WES attempts since the alteration in the nucleotide did not change the amino acids, due to creation of a new ...
