Genes affected

SDF2 (HGNC:10675): (stromal cell derived factor 2) The protein encoded by this gene is believed to be a secretory protein. It has regions of similarity to hydrophilic segments of yeast mannosyltransferases. Its expression is ubiquitous and the gene appears to be relatively conserved among mammals. Alternate splicing results in both coding and non-coding variants. A pseudogene of this gene is located on chromosome 15. [provided by RefSeq, Dec 2011]

Jan 19, 2022

The c.535A>G (p.M179V) alteration is located in exon 3 (coding exon 3) of the SDF2 gene. This alteration results from a A to G substitution at nucleotide position 535, causing the methionine (M) at amino acid position 179 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
