Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.347C>G (p.A116G) alteration is located in exon 5 (coding exon 5) of the SFT2D2 gene. This alteration results from a C to G substitution at nucleotide position 347, causing the alanine (A) at amino acid position 116 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
