not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 09, 2024The c.2138C>T (p.A713V) alteration is located in exon 18 (coding exon 17) of the SFMBT2 gene. This alteration results from a C to T substitution at nucleotide position 2138, causing the alanine (A) at amino acid position 713 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
