Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.191T>C (p.F64S) alteration is located in exon 2 (coding exon 2) of the TM6SF1 gene. This alteration results from a T to C substitution at nucleotide position 191, causing the phenylalanine (F) at amino acid position 64 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
