Genes affected

CSF1 (HGNC:2432): (colony stimulating factor 1) The protein encoded by this gene is a cytokine that controls the production, differentiation, and function of macrophages. The active form of the protein is found extracellularly as a disulfide-linked homodimer, and is thought to be produced by proteolytic cleavage of membrane-bound precursors. The encoded protein may be involved in development of the placenta. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]

Collection Method:clinical testing

The c.760C>T (p.P254S) alteration is located in exon 1 (coding exon 1) of the CSF1 gene. This alteration results from a C to T substitution at nucleotide position 760, causing the proline (P) at amino acid position 254 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
