Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2021The c.290C>T (p.T97M) alteration is located in exon 3 (coding exon 3) of the TBC1D22A gene. This alteration results from a C to T substitution at nucleotide position 290, causing the threonine (T) at amino acid position 97 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
