Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.1478T>C (p.M493T) alteration is located in exon 12 (coding exon 12) of the TM7SF3 gene. This alteration results from a T to C substitution at nucleotide position 1478, causing the methionine (M) at amino acid position 493 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
