Variant chr17-49224362-G-T details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_178500.4(PHOSPHO1):c.688C>A(p.Arg230Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000283 in 1,411,824 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. R230C) has been classified as Uncertain significance.

The c.763C>A (p.R255S) alteration is located in exon 3 (coding exon 1) of the PHOSPHO1 gene. This alteration results from a C to A substitution at nucleotide position 763, causing the arginine (R) at amino acid position 255 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
