Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_152259.4(TICRR):ā€‹c.821C>Gā€‹(p.Pro274Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000137 in 1,461,894 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P274Q) has been classified as Uncertain significance.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.821C>G (p.P274R) alteration is located in exon 2 (coding exon 2) of the TICRR gene. This alteration results from a C to G substitution at nucleotide position 821, causing the proline (P) at amino acid position 274 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
