Genes affected

SDF4 (HGNC:24188): (stromal cell derived factor 4) This gene encodes a stromal cell derived factor that is a member of the CREC protein family. The encoded protein contains six EF-hand motifs and calcium-binding motifs. This protein localizes to the Golgi lumen and may be involved in regulating calcium dependent cellular activities.

The c.1010A>G (p.E337G) alteration is located in exon 7 (coding exon 6) of the SDF4 gene. This alteration results from a A to G substitution at nucleotide position 1010, causing the glutamic acid (E) at amino acid position 337 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
