Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 28, 2021The c.2272C>T (p.R758W) alteration is located in exon 19 (coding exon 18) of the SFMBT2 gene. This alteration results from a C to T substitution at nucleotide position 2272, causing the arginine (R) at amino acid position 758 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
