Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.764A>G (p.N255S) alteration is located in exon 6 (coding exon 6) of the TM7SF3 gene. This alteration results from a A to G substitution at nucleotide position 764, causing the asparagine (N) at amino acid position 255 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
