Genes affected

CFAP57 (HGNC:26485): (cilia and flagella associated protein 57) This protein encoded by this gene belongs to the WD repeat-containing family of proteins, which function in the formation of protein-protein complexes in a variety of biological pathways. This family member is thought to function in craniofacial development, possibly in the fusion of lip and palate. A missense mutation in this gene is associated with Van der Woude syndrome 2. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Aug 2011]

EBNA1BP2 (HGNC:15531): (EBNA1 binding protein 2) Enables RNA binding activity. Predicted to be involved in rRNA processing and ribosomal large subunit biogenesis. Located in chromosome and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

LOC105378685 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.005825013).
• BS1: Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0138 (19304/1397560) while in subpopulation NFE AF = 0.0159 (17183/1078508). AF 95% confidence interval is 0.0157. There are 171 homozygotes in GnomAdExome4. There are 9221 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 13 AR gene
