Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.1181C>A (p.T394N) alteration is located in exon 9 (coding exon 9) of the TM7SF3 gene. This alteration results from a C to A substitution at nucleotide position 1181, causing the threonine (T) at amino acid position 394 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
