Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 27, 2023The c.307G>A (p.V103M) alteration is located in exon 3 (coding exon 3) of the TLCD1 gene. This alteration results from a G to A substitution at nucleotide position 307, causing the valine (V) at amino acid position 103 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
