Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_003923.3(FOXH1):c.47C>T(p.Ser16Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000409 in 1,422,416 control chromosomes in the GnomAD database, including 2 homozygotes. 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 Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. S16S) has been classified as Likely benign.

Genes affected

FOXH1 (HGNC:3814): (forkhead box H1) FOXH1 encodes a human homolog of Xenopus forkhead activin signal transducer-1. FOXH1 protein binds SMAD2 and activates an activin response element via binding the DNA motif TGT(G/T)(T/G)ATT. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.006274283).

BP6

Variant 8-144475710-G-A is Benign according to our data. Variant chr8-144475710-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 259200.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00218 (332/152292) while in subpopulation AFR AF = 0.00775 (322/41562). AF 95% confidence interval is 0.00705. There are 2 homozygotes in GnomAd4. There are 167 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 2 Unknown gene
