Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2022The c.1177T>C (p.F393L) alteration is located in exon 9 (coding exon 9) of the TM7SF3 gene. This alteration results from a T to C substitution at nucleotide position 1177, causing the phenylalanine (F) at amino acid position 393 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
