Variant summary
Our verdict is Pathogenic. Variant got 17 ACMG points: 17P and 0B. PM1PM2PP2PP3_StrongPP5_Very_Strong
The NM_022455.5(NSD1):c.4817G>A(p.Cys1606Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. C1606C) has been classified as Likely benign.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 30, 2022 | This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 1606 of the NSD1 protein (p.Cys1606Tyr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Sotos syndrome (PMID: 26690673). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 159345). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NSD1 protein function. For these reasons, this variant has been classified as Pathogenic. - |
