Variant 17-64859887-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM2PP2BP4_Strong

The NM_199340.5(LRRC37A3):c.4259A>G(p.Asn1420Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000558 in 1,613,310 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/20 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. N1420D) has been classified as Uncertain significance.

Nov 02, 2023

The c.4259A>G (p.N1420S) alteration is located in exon 11 (coding exon 9) of the LRRC37A3 gene. This alteration results from a A to G substitution at nucleotide position 4259, causing the asparagine (N) at amino acid position 1420 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
