Genes affected
CLTC (HGNC:2092): (clathrin heavy chain) Clathrin is a major protein component of the cytoplasmic face of intracellular organelles, called coated vesicles and coated pits. These specialized organelles are involved in the intracellular trafficking of receptors and endocytosis of a variety of macromolecules. The basic subunit of the clathrin coat is composed of three heavy chains and three light chains. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.3).
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000404 (59/1461796) while in subpopulation NFE AF = 0.0000522 (58/1111942). AF 95% confidence interval is 0.0000409. There are 0 homozygotes in GnomAdExome4. There are 29 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAdExome4 at 59 AD gene.
