Genes affected

PAX1 (HGNC:8615): (paired box 1) This gene is a member of the paired box (PAX) family of transcription factors. Members of the PAX family typically contain a paired box domain and a paired-type homeodomain. These genes play critical roles during fetal development. This gene plays a role in pattern formation during embryogenesis and may be essential for development of the vertebral column. This gene is silenced by methylation in ovarian and cervical cancers and may be a tumor suppressor gene. Mutations in this gene are also associated with vertebral malformations.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.33474427).

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000064 (7/1093044) while in subpopulation SAS AF= 0.000357 (7/19620). AF 95% confidence interval is 0.000167. There are 0 homozygotes in gnomad4_exome. There are 4 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.8T>C (p.F3S) alteration is located in exon 1 (coding exon 1) of the PAX1 gene. This alteration results from a T to C substitution at nucleotide position 8, causing the phenylalanine (F) at amino acid position 3 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
