Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 30, 2023The c.254C>A (p.A85E) alteration is located in exon 5 (coding exon 5) of the SPX gene. This alteration results from a C to A substitution at nucleotide position 254, causing the alanine (A) at amino acid position 85 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
