Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2022The c.1172A>G (p.N391S) alteration is located in exon 7 (coding exon 6) of the BLZF1 gene. This alteration results from a A to G substitution at nucleotide position 1172, causing the asparagine (N) at amino acid position 391 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
