Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.188C>T (p.T63I) 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 188, causing the threonine (T) at amino acid position 63 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
