Variant 19-49108114-G-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_003089.6(SNRNP70):c.985G>T(p.Asp329Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.000029 in 1,549,944 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. D329H) has been classified as Uncertain significance.

Ambry Genetics

Nov 10, 2022

The c.985G>T (p.D329Y) alteration is located in exon 10 (coding exon 9) of the SNRNP70 gene. This alteration results from a G to T substitution at nucleotide position 985, causing the aspartic acid (D) at amino acid position 329 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
