Collection Method: clinical testing

The c.130G>A (p.G44S) alteration is located in exon 3 (coding exon 1) of the SLC35A4 gene. This alteration results from a G to A substitution at nucleotide position 130, causing the glycine (G) at amino acid position 44 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
