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.898G>A (p.A300T) alteration is located in exon 6 (coding exon 5) of the SDF4 gene. This alteration results from a G to A substitution at nucleotide position 898, causing the alanine (A) at amino acid position 300 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
