Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 30, 2023The c.611C>T (p.T204I) alteration is located in exon 6 (coding exon 6) of the SAMSN1 gene. This alteration results from a C to T substitution at nucleotide position 611, causing the threonine (T) at amino acid position 204 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
