Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2023The c.2065G>T (p.A689S) alteration is located in exon 18 (coding exon 17) of the SFMBT2 gene. This alteration results from a G to T substitution at nucleotide position 2065, causing the alanine (A) at amino acid position 689 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
