Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.778T>C (p.Y260H) alteration is located in exon 4 (coding exon 4) of the FAXC gene. This alteration results from a T to C substitution at nucleotide position 778, causing the tyrosine (Y) at amino acid position 260 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
