Genes affected

SCIMP (HGNC:33504): (SLP adaptor and CSK interacting membrane protein) This gene encodes a transmembrane adaptor protein that is expressed in antigen-presenting cells and is localized in the immunologic synapse. The encoded protein is involved in major histocompatibility complex class II signal transduction and immune synapse formation. Alternatively spliced transcript variants have been found for this gene.

Ambry Genetics

Jan 29, 2024

The c.227C>T (p.S76L) alteration is located in exon 4 (coding exon 4) of the SCIMP gene. This alteration results from a C to T substitution at nucleotide position 227, causing the serine (S) at amino acid position 76 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
