Variant 4-185372979-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_001377440.1(LRP2BP):c.680C>A(p.Thr227Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000744 in 1,613,808 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 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. T227M) has been classified as Uncertain significance.

Ambry Genetics

Dec 27, 2023

The c.680C>A (p.T227K) alteration is located in exon 6 (coding exon 6) of the LRP2BP gene. This alteration results from a C to A substitution at nucleotide position 680, causing the threonine (T) at amino acid position 227 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
