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.929T>C (p.M310T) alteration is located in exon 7 (coding exon 6) of the SDF4 gene. This alteration results from a T to C substitution at nucleotide position 929, causing the methionine (M) at amino acid position 310 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
