Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2022The c.2218G>A (p.A740T) alteration is located in exon 18 (coding exon 12) of the ST18 gene. This alteration results from a G to A substitution at nucleotide position 2218, causing the alanine (A) at amino acid position 740 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
