Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.14G>A (p.C5Y) alteration is located in exon 3 (coding exon 1) of the TSPAN18 gene. This alteration results from a G to A substitution at nucleotide position 14, causing the cysteine (C) at amino acid position 5 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
