Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 16, 2024The c.106G>C (p.V36L) alteration is located in exon 4 (coding exon 2) of the TSPAN18 gene. This alteration results from a G to C substitution at nucleotide position 106, causing the valine (V) at amino acid position 36 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
