Variant chr16-71649009-G-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_015020.3(PHLPP2):c.3853C>A(p.His1285Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,812 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. H1285R) has been classified as Likely benign.

The c.3853C>A (p.H1285N) alteration is located in exon 18 (coding exon 18) of the PHLPP2 gene. This alteration results from a C to A substitution at nucleotide position 3853, causing the histidine (H) at amino acid position 1285 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
