Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2021The c.460G>A (p.E154K) alteration is located in exon 7 (coding exon 5) of the TSPAN18 gene. This alteration results from a G to A substitution at nucleotide position 460, causing the glutamic acid (E) at amino acid position 154 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
