Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 16, 2022The c.821C>A (p.P274Q) alteration is located in exon 2 (coding exon 2) of the TICRR gene. This alteration results from a C to A substitution at nucleotide position 821, causing the proline (P) at amino acid position 274 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
