Collection Method: clinical testing

The c.286G>C (p.D96H) alteration is located in exon 2 (coding exon 2) of the SWSAP1 gene. This alteration results from a G to C substitution at nucleotide position 286, causing the aspartic acid (D) at amino acid position 96 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
