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.

Collection Method:clinical testing

The c.650C>T (p.T217M) alteration is located in exon 5 (coding exon 4) of the SDF4 gene. This alteration results from a C to T substitution at nucleotide position 650, causing the threonine (T) at amino acid position 217 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
