Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.2308G>A (p.V770M) alteration is located in exon 19 (coding exon 18) of the SFMBT2 gene. This alteration results from a G to A substitution at nucleotide position 2308, causing the valine (V) at amino acid position 770 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
