Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The ENST00000355192.8(MSRB3):c.74C>T(p.Ala25Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000354 in 1,412,264 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. A25S) has been classified as Uncertain significance.

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 26, 2022 | The c.74C>T (p.A25V) alteration is located in exon 1 (coding exon 1) of the MSRB3 gene. This alteration results from a C to T substitution at nucleotide position 74, causing the alanine (A) at amino acid position 25 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
