Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.752A>G (p.N251S) 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 752, causing the asparagine (N) at amino acid position 251 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
