Variant 8-143726297-C-T details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_198488.5(FAM83H):c.3164G>A(p.Arg1055His) variant causes a missense change. The variant allele was found at a frequency of 0.00000186 in 1,611,994 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. R1055C) has been classified as Uncertain significance.

The c.3164G>A (p.R1055H) alteration is located in exon 5 (coding exon 4) of the FAM83H gene. This alteration results from a G to A substitution at nucleotide position 3164, causing the arginine (R) at amino acid position 1055 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
