Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2023The c.51G>C (p.K17N) alteration is located in exon 2 (coding exon 2) of the SPATA33 gene. This alteration results from a G to C substitution at nucleotide position 51, causing the lysine (K) at amino acid position 17 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
