Collection Method:clinical testing

The c.236G>A (p.R79K) alteration is located in exon 3 (coding exon 3) of the SPAG11A gene. This alteration results from a G to A substitution at nucleotide position 236, causing the arginine (R) at amino acid position 79 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
