Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.2663G>A (p.R888Q) alteration is located in exon 22 (coding exon 16) of the ST18 gene. This alteration results from a G to A substitution at nucleotide position 2663, causing the arginine (R) at amino acid position 888 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
