Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2021The c.1195T>C (p.F399L) alteration is located in exon 10 (coding exon 7) of the GTDC1 gene. This alteration results from a T to C substitution at nucleotide position 1195, causing the phenylalanine (F) at amino acid position 399 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
