Genes affected

LIF (HGNC:6596): (LIF interleukin 6 family cytokine) The protein encoded by this gene is a pleiotropic cytokine with roles in several different systems. It is involved in the induction of hematopoietic differentiation in normal and myeloid leukemia cells, induction of neuronal cell differentiation, regulator of mesenchymal to epithelial conversion during kidney development, and may also have a role in immune tolerance at the maternal-fetal interface. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Mar 2012]

The c.172A>G (p.S58G) alteration is located in exon 2 (coding exon 2) of the LIF gene. This alteration results from a A to G substitution at nucleotide position 172, causing the serine (S) at amino acid position 58 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
