Collection Method: clinical testing

The c.911G>A (p.R304H) alteration is located in exon 5 (coding exon 4) of the SPATC1L gene. This alteration results from a G to A substitution at nucleotide position 911, causing the arginine (R) at amino acid position 304 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
