Variant 12-57225067-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_007224.4(NXPH4):c.247G>A(p.Ala83Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000949 in 1,474,616 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 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. A83D) has been classified as Uncertain significance.

Ambry Genetics

Dec 17, 2023

The c.247G>A (p.A83T) alteration is located in exon 2 (coding exon 2) of the NXPH4 gene. This alteration results from a G to A substitution at nucleotide position 247, causing the alanine (A) at amino acid position 83 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
