not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2022The c.411G>T (p.L137F) alteration is located in exon 2 (coding exon 1) of the TTC24 gene. This alteration results from a G to T substitution at nucleotide position 411, causing the leucine (L) at amino acid position 137 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
