Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2024The c.2978T>C (p.V993A) alteration is located in exon 7 (coding exon 7) of the FGD6 gene. This alteration results from a T to C substitution at nucleotide position 2978, causing the valine (V) at amino acid position 993 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
