Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 20, 2023The c.962C>T (p.T321I) alteration is located in exon 10 (coding exon 10) of the TM6SF1 gene. This alteration results from a C to T substitution at nucleotide position 962, causing the threonine (T) at amino acid position 321 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
