Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 13P and 1B. PM1PM5PP3PP5_Very_StrongBP4
The NM_001492.6(GDF1):āc.1091T>Cā(p.Met364Thr) variant causes a missense change. The variant allele was found at a frequency of 0.000209 in 1,571,682 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 Likely pathogenic (ā ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M364I) has been classified as Likely pathogenic.

Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 08, 2023 | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. 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 GDF1 protein function. ClinVar contains an entry for this variant (Variation ID: 522571). This missense change has been observed in individual(s) with congenital heart disease and/or abnormality of the cardiovascular system (PMID: 26633542, 28991257, 34958143). It is commonly reported in individuals of Ashkenazi Jewish ancestry (PMID: 28991257). This variant is present in population databases (rs374016704, gnomAD 0.9%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 364 of the GDF1 protein (p.Met364Thr). - |

Heart, malformation of Pathogenic:1
Likely pathogenic, no assertion criteria provided | curation | Reproductive Health Research and Development, BGI Genomics | Jan 06, 2020 | NM_001492.4:c.1091T>C in the GDF1 gene has an allele frequency of 0.009 in Ashkenazi Jewish subpopulation in the gnomAD database. This variant has been reported to be a common cause of congenital heart disease in the Ashkenazi Jewish population and has been found in homozygosity in 10 affected individuals (PMID: 28991257). Additional evidence supports homozygosity for p.Met364Thr in CHD risk among Ashkenazim. p.Met364Thr shows remarkable violation of Hardy Weinberg equilibrium among Ashkenazi CHD cases, (P = 5.5x10-38, 1-df chi-square test with Yates correction). In contrast, among 302 Ashkenazi autism parental controls and 926 additional Ashkenazi adults from an independent cohort without CHD, there were no homozygotes and 12 heterozygotes (two-sided Fisher's Exact P = 2.8x10-9). Pathogenic computational verdict because pathogenic predictions from DANN, DEOGEN2, MutationTaster, REVEL and SIFTT. We interprete this variant as Pathogenic/Likely pathogenic.
