Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2022The c.643C>A (p.H215N) alteration is located in exon 2 (coding exon 2) of the FAM120AOS gene. This alteration results from a C to A substitution at nucleotide position 643, causing the histidine (H) at amino acid position 215 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
