Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.8C>T (p.T3M) alteration is located in exon 1 (coding exon 1) of the SPATA33 gene. This alteration results from a C to T substitution at nucleotide position 8, causing the threonine (T) at amino acid position 3 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
