Variant 10-23119428-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong

The ENST00000376510.8(MSRB2):c.421C>T(p.Arg141Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000178 in 1,461,592 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R141H) has been classified as Uncertain significance.

The c.421C>T (p.R141C) alteration is located in exon 4 (coding exon 4) of the MSRB2 gene. This alteration results from a C to T substitution at nucleotide position 421, causing the arginine (R) at amino acid position 141 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
