Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2023The c.353C>G (p.A118G) alteration is located in exon 4 (coding exon 4) of the TLDC2 gene. This alteration results from a C to G substitution at nucleotide position 353, causing the alanine (A) at amino acid position 118 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
