Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2021The c.902C>T (p.T301I) alteration is located in exon 4 (coding exon 3) of the TMUB2 gene. This alteration results from a C to T substitution at nucleotide position 902, causing the threonine (T) at amino acid position 301 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
