Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2024The c.748G>A (p.G250S) alteration is located in exon 4 (coding exon 4) of the FAXC gene. This alteration results from a G to A substitution at nucleotide position 748, causing the glycine (G) at amino acid position 250 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
