Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000153.4(GALC):βc.1012delβ(p.Glu338AsnfsTer21) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000274 in 1,461,328 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (β β ). Synonymous variant affecting the same amino acid position (i.e. E338E) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 09, 2023 | This sequence change creates a premature translational stop signal (p.Glu338Asnfs*21) in the GALC gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GALC are known to be pathogenic (PMID: 7437911, 9272171, 16607461). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with Krabbe disease (PMID: 9338580). This variant is also known as 964delG. ClinVar contains an entry for this variant (Variation ID: 370416). For these reasons, this variant has been classified as Pathogenic. - |
