Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.121C>T (p.R41C) alteration is located in exon 4 (coding exon 2) of the TSNAXIP1 gene. This alteration results from a C to T substitution at nucleotide position 121, causing the arginine (R) at amino acid position 41 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
