Genetic Variant SRFBP1:p.Ala101Asp (chr5-122019291-C-A) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3

The NM_152546.3(SRFBP1):c.302C>A(p.Ala101Asp) variant causes a missense change. The variant allele was found at a frequency of 0.0000571 in 1,612,254 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. A101V) has been classified as Uncertain significance.
