Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 04, 2023The c.707A>G (p.N236S) alteration is located in exon 4 (coding exon 4) of the FRZB gene. This alteration results from a A to G substitution at nucleotide position 707, causing the asparagine (N) at amino acid position 236 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
