Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2021The c.817C>T (p.L273F) alteration is located in exon 4 (coding exon 4) of the FAXC gene. This alteration results from a C to T substitution at nucleotide position 817, causing the leucine (L) at amino acid position 273 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
