Genes affected

CTNNBL1 (HGNC:15879): (catenin beta like 1) The protein encoded by this gene is a component of the pre-mRNA-processing factor 19-cell division cycle 5-like (PRP19-CDC5L) protein complex, which activates pre-mRNA splicing and is an integral part of the spliceosome. The encoded protein is also a nuclear localization sequence binding protein, and binds to activation-induced deaminase and is important for antibody diversification. This gene may also be associated with the development of obesity. Alternative splicing results in multiple transcript variants. A pseudogene of this gene has been defined on the X chromosome.

Sep 27, 2024

The c.434C>T (p.S145L) alteration is located in exon 4 (coding exon 4) of the CTNNBL1 gene. This alteration results from a C to T substitution at nucleotide position 434, causing the serine (S) at amino acid position 145 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
