Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.938T>C (p.I313T) alteration is located in exon 10 (coding exon 10) of the TM6SF1 gene. This alteration results from a T to C substitution at nucleotide position 938, causing the isoleucine (I) at amino acid position 313 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
