ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000447 (68/152132) while in subpopulation AFR AF= 0.00135 (56/41494). AF 95% confidence interval is 0.00107. There are 0 homozygotes in gnomad4. There are 29 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 22, 2023The c.413C>T (p.P138L) alteration is located in exon 6 (coding exon 6) of the PTCD3 gene. This alteration results from a C to T substitution at nucleotide position 413, causing the proline (P) at amino acid position 138 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
