Variant 17-49224460-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_178500.4(PHOSPHO1):c.590G>A(p.Arg197His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000705 in 1,560,462 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 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. R197L) has been classified as Uncertain significance.

The c.665G>A (p.R222H) alteration is located in exon 3 (coding exon 1) of the PHOSPHO1 gene. This alteration results from a G to A substitution at nucleotide position 665, causing the arginine (R) at amino acid position 222 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
