dbSNP rs1297118863: FAH:p.Gly404Ser (chr15-80186159-G-A) – ACMG Classification: Pathogenic (18 pts)

Variant summary

Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong

The NM_000137.4(FAH):c.1210G>A(p.Gly404Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,614,020 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 Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G404R) has been classified as Likely pathogenic.

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 18 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 9 uncertain in NM_000137.4

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr15-80186159-G-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 1348938.Status of the report is criteria_provided_single_submitter, 1 stars.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.982

PP5

Variant 15-80186159-G-A is Pathogenic according to our data. Variant chr15-80186159-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 459903.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
