Genetic Variant CFAP46:p.Ala2595Val (chr10-132808785-G-A) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001200049.3(CFAP46):c.7784C>T(p.Ala2595Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000313 in 1,599,740 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A2595T) has been classified as Uncertain significance.

Collection Method:clinical testing

The c.2720C>T (p.A907V) alteration is located in exon 23 (coding exon 23) of the CFAP46 gene. This alteration results from a C to T substitution at nucleotide position 2720, causing the alanine (A) at amino acid position 907 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
