Genes affected

CBLC (HGNC:15961): (Cbl proto-oncogene C) This gene encodes a member of the Cbl family of E3 ubiquitin ligases. Cbl proteins play important roles in cell signaling through the ubiquitination and subsequent downregulation of tyrosine kinases. Expression of this gene may be restricted to epithelial cells, and alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The c.344C>T (p.S115F) alteration is located in exon 1 (coding exon 1) of the CBLC gene. This alteration results from a C to T substitution at nucleotide position 344, causing the serine (S) at amino acid position 115 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
