Genes affected
CFAP53 (HGNC:26530): (cilia and flagella associated protein 53) This gene belongs to the CFAP53 family. It was found to be differentially expressed by the ciliated cells of frog epidermis and in skin fibroblasts from human. Mutations in this gene are associated with visceral heterotaxy-6, which implicates this gene in determination of left-right asymmetric patterning. [provided by RefSeq, Aug 2015]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.016695976).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000217 (33/152176) while in subpopulation AFR AF= 0.000796 (33/41438). AF 95% confidence interval is 0.000583. There are 0 homozygotes in gnomad4. There are 16 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2024The c.1445T>C (p.M482T) alteration is located in exon 8 (coding exon 8) of the CCDC11 gene. This alteration results from a T to C substitution at nucleotide position 1445, causing the methionine (M) at amino acid position 482 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
