Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.346G>A (p.E116K) alteration is located in exon 2 (coding exon 2) of the SBSPON gene. This alteration results from a G to A substitution at nucleotide position 346, causing the glutamic acid (E) at amino acid position 116 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
