Genes affected

MYDGF (HGNC:16948): (myeloid derived growth factor) The protein encoded by this gene was previously thought to support proliferation of lymphoid cells and was considered an interleukin. However, this activity has not been reproducible and the function of this protein is currently unknown. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.358G>A (p.A120T) alteration is located in exon 4 (coding exon 4) of the MYDGF gene. This alteration results from a G to A substitution at nucleotide position 358, causing the alanine (A) at amino acid position 120 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
