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.577A>G (p.T193A) alteration is located in exon 7 (coding exon 7) of the STAM gene. This alteration results from a A to G substitution at nucleotide position 577, causing the threonine (T) at amino acid position 193 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
