Ambry Genetics | RCV004030362 | SCV001174656 | uncertain significance | not specified | 2023-11-22 | criteria provided, single submitter | clinical testing | The p.M1? variant (also known as c.1A>C) is located in coding exon 1 of the GALNT12 gene and results from an A to C substitution at nucleotide position 1.This alters the methionine residue at the initiation codon (ATG). The c.1A>C alteration is expected to modify the initiation codon (ATG) resulting in either loss of translation initiation, N-terminal truncation, or cause a shift in the mRNA reading frame. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. |

RCV001860753 | SCV002160888 | uncertain significance | not provided | 2021-06-29 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals with GALNT12-related conditions. ClinVar contains an entry for this variant (Variation ID: 820494). 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. Experimental studies have shown that disruption of the initiator codon affects GALNT12 protein function (PMID: 19617566). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change affects the initiator methionine of the GALNT12 mRNA. The next in-frame methionine is located at codon 65. |
