dbSNP rs181173877: FCHO1:c.-121C>A (chr19-17762764-C-A) – ACMG Classification: Benign (-11 pts)

Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 0P and 11B. BP4_StrongBP6_ModerateBP7BS1

The NM_015122.3(FCHO1):c.30C>A(p.Gly10Gly) variant causes a splice region, synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000304 in 1,611,688 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Likely benign (★). Synonymous variant affecting the same amino acid position (i.e. G10G) has been classified as Likely benign.

Genes affected

FCHO1 (HGNC:29002): (FCH and mu domain containing endocytic adaptor 1) Enables AP-2 adaptor complex binding activity. Involved in clathrin coat assembly and clathrin-dependent endocytosis. Located in cytosol; nucleoplasm; and plasma membrane. Is active in clathrin-coated pit. Implicated in primary immunodeficiency disease. [provided by Alliance of Genome Resources, Apr 2022]
