Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 20, 2023The c.245G>T (p.C82F) alteration is located in exon 3 (coding exon 3) of the TLDC2 gene. This alteration results from a G to T substitution at nucleotide position 245, causing the cysteine (C) at amino acid position 82 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
