Variant summary
Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1PP3_StrongPP5_Moderate
The NM_004387.4(NKX2-5):c.533C>T(p.Thr178Met) variant causes a missense change involving the alteration of a conserved nucleotide. In-silico tool predicts a pathogenic outcome for this variant. 12/20 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. T178T) has been classified as Likely benign.

Genes affected
NKX2-5 (HGNC:2488): (NK2 homeobox 5) This gene encodes a homeobox-containing transcription factor. This transcription factor functions in heart formation and development. Mutations in this gene cause atrial septal defect with atrioventricular conduction defect, and also tetralogy of Fallot, which are both heart malformation diseases. Mutations in this gene can also cause congenital hypothyroidism non-goitrous type 5, a non-autoimmune condition. Alternative splicing results in multiple transcript variants.

Pathogenic, no assertion criteria provided | literature only | OMIM | Jul 15, 2005 | - - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Feb 22, 2022 | This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 178 of the NKX2-5 protein (p.Thr178Met). For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects NKX2-5 function (PMID: 10948187, 21677783, 27013732). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 9004). This missense change has been observed in individuals with NKX2-5-related conditions (PMID: 9651244, 12798584, 15810002). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). - |
