Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.193C>T (p.R65W) alteration is located in exon 1 (coding exon 1) of the SPATA3 gene. This alteration results from a C to T substitution at nucleotide position 193, causing the arginine (R) at amino acid position 65 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
