Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 27, 2022The c.854C>T (p.P285L) alteration is located in exon 6 (coding exon 5) of the BLZF1 gene. This alteration results from a C to T substitution at nucleotide position 854, causing the proline (P) at amino acid position 285 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
