Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 14, 2024The c.166A>C (p.N56H) alteration is located in exon 3 (coding exon 1) of the FAM103A1 gene. This alteration results from a A to C substitution at nucleotide position 166, causing the asparagine (N) at amino acid position 56 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
