ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), HECTD4. . Gene score misZ 6.9421 (greater than the threshold 3.09). Trascript score misZ 8.6089 (greater than threshold 3.09). GenCC has associacion of gene with neurodevelopmental disorder with seizures, spasticity, and complete or partial agenesis of the corpus callosum.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.805

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2024The c.12271C>T (p.R4091W) alteration is located in exon 73 (coding exon 72) of the HECTD4 gene. This alteration results from a C to T substitution at nucleotide position 12271, causing the arginine (R) at amino acid position 4091 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
