Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.306G>C (p.L102F) alteration is located in exon 3 (coding exon 3) of the TLCD2 gene. This alteration results from a G to C substitution at nucleotide position 306, causing the leucine (L) at amino acid position 102 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
