Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM1BP6
The NM_003924.4(PHOX2B):c.865G>A(p.Gly289Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0000255 in 1,608,412 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G289D) has been classified as Uncertain significance.

Submissions by phenotype
Haddad syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 06, 2023 | This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 289 of the PHOX2B protein (p.Gly289Ser). This variant is present in population databases (rs769663483, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with PHOX2B-related conditions. ClinVar contains an entry for this variant (Variation ID: 576023). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Dec 28, 2022 | Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Identified in a pediatric patient with leukemia (Zhang et al., 2015); This variant is associated with the following publications: (PMID: 26580448) - |
Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | May 31, 2022 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
