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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 11, 2024The c.145G>A (p.G49R) alteration is located in exon 1 (coding exon 1) of the SDF2 gene. This alteration results from a G to A substitution at nucleotide position 145, causing the glycine (G) at amino acid position 49 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
