Genes affected
ST7 (HGNC:11351): (suppression of tumorigenicity 7) The gene for this product maps to a region on chromosome 7 identified as an autism-susceptibility locus. Mutation screening of the entire coding region in autistic individuals failed to identify phenotype-specific variants, suggesting that coding mutations for this gene are unlikely to be involved in the etiology of autism. The function of this gene product has not been determined. Transcript variants encoding different isoforms of this protein have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 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), ST7. . Gene score misZ 3.3795 (greater than the threshold 3.09). Trascript score misZ 3.691 (greater than threshold 3.09). GenCC has associacion of gene with developmental and epileptic encephalopathy.
BP4
Computational evidence support a benign effect (MetaRNN=0.33191922).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.376A>T (p.N126Y) alteration is located in exon 3 (coding exon 3) of the ST7 gene. This alteration results from a A to T substitution at nucleotide position 376, causing the asparagine (N) at amino acid position 126 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
