Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.302C>T (p.S101F) alteration is located in exon 3 (coding exon 2) of the BLZF1 gene. This alteration results from a C to T substitution at nucleotide position 302, causing the serine (S) at amino acid position 101 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
