Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 17, 2023The c.92T>G (p.M31R) alteration is located in exon 2 (coding exon 2) of the SPATA33 gene. This alteration results from a T to G substitution at nucleotide position 92, causing the methionine (M) at amino acid position 31 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
