Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 15, 2021The c.265G>C (p.G89R) alteration is located in exon 4 (coding exon 4) of the SPAG7 gene. This alteration results from a G to C substitution at nucleotide position 265, causing the glycine (G) at amino acid position 89 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
