Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_022356.4(P3H1):c.1529A>G(p.Asn510Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000171 in 1,614,108 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N510T) has been classified as Uncertain significance.

Genes affected

P3H1 (HGNC:19316): (prolyl 3-hydroxylase 1) This gene encodes an enzyme that is a member of the collagen prolyl hydroxylase family. These enzymes are localized to the endoplasmic reticulum and their activity is required for proper collagen synthesis and assembly. Mutations in this gene are associated with osteogenesis imperfecta type VIII. Three alternatively spliced transcript variants encoding different isoforms have been described. Other variants may exist, but their biological validity has not been determined. [provided by RefSeq, Aug 2011]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.007150173).

BP6

Variant 1-42752314-T-C is Benign according to our data. Variant chr1-42752314-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 289042.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000893 (136/152266) while in subpopulation AFR AF = 0.00325 (135/41542). AF 95% confidence interval is 0.0028. There are 1 homozygotes in GnomAd4. There are 64 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
