Variant 1-1179250-G-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_001130045.2(TTLL10):c.35G>C(p.Arg12Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000194 in 1,550,010 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R12W) has been classified as Uncertain significance.

Ambry Genetics

Jul 25, 2023

The c.35G>C (p.R12P) alteration is located in exon 4 (coding exon 1) of the TTLL10 gene. This alteration results from a G to C substitution at nucleotide position 35, causing the arginine (R) at amino acid position 12 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
