Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.908T>C (p.V303A) alteration is located in exon 10 (coding exon 10) of the ITFG1 gene. This alteration results from a T to C substitution at nucleotide position 908, causing the valine (V) at amino acid position 303 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
