Genes affected

STAM (HGNC:11357): (signal transducing adaptor molecule) This gene encodes a member of the signal-transducing adaptor molecule family. These proteins mediate downstream signaling of cytokine receptors and also play a role in ER to Golgi trafficking by interacting with the coat protein II complex. The encoded protein also associates with hepatocyte growth factor-regulated substrate to form the endosomal sorting complex required for transport-0 (ESCRT-0), which sorts ubiquitinated membrane proteins to the ESCRT-1 complex for lysosomal degradation. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Feb 2011]

The c.977T>C (p.L326P) alteration is located in exon 10 (coding exon 10) of the STAM gene. This alteration results from a T to C substitution at nucleotide position 977, causing the leucine (L) at amino acid position 326 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
