Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2022The c.683C>A (p.T228N) alteration is located in exon 5 (coding exon 5) of the SSPO gene. This alteration results from a C to A substitution at nucleotide position 683, causing the threonine (T) at amino acid position 228 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
