Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 31, 2023The c.237C>A (p.S79R) alteration is located in exon 3 (coding exon 3) of the SPATA33 gene. This alteration results from a C to A substitution at nucleotide position 237, causing the serine (S) at amino acid position 79 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
