Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.2311C>T (p.R771C) 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 2311, causing the arginine (R) at amino acid position 771 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
