Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2021The c.2444A>G (p.H815R) alteration is located in exon 1 (coding exon 1) of the FSCB gene. This alteration results from a A to G substitution at nucleotide position 2444, causing the histidine (H) at amino acid position 815 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
