Variant 19-46722857-A-G 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_013403.3(STRN4):c.1859T>C(p.Met620Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000684 in 1,461,614 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 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. M620V) has been classified as Benign.

Ambry Genetics

Nov 18, 2022

The c.1880T>C (p.M627T) alteration is located in exon 14 (coding exon 14) of the STRN4 gene. This alteration results from a T to C substitution at nucleotide position 1880, causing the methionine (M) at amino acid position 627 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
