Genetic Variant SDAD1:p.Asn88Ser (chr4-75981403-T-C) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate

The NM_018115.4(SDAD1):c.263A>G(p.Asn88Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0000335 in 1,613,784 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N88I) has been classified as Uncertain significance.
