Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.32C>G (p.S11C) alteration is located in exon 1 (coding exon 1) of the SPAG7 gene. This alteration results from a C to G substitution at nucleotide position 32, causing the serine (S) at amino acid position 11 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
