NM_001367956.1:c.517C>T

Variant summary

Our verdict is Benign. The variant received -12 ACMG points: 0P and 12B. BP4_StrongBA1

The NM_001367956.1(FAM170A):​c.517C>T​(p.Pro173Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.446 in 1,613,780 control chromosomes in the GnomAD database, including 162,208 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/21 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. P173L) has been classified as Uncertain significance.

Genes affected
FAM170A (HGNC:27963): (family with sequence similarity 170 member A) Predicted to enable DNA binding activity and metal ion binding activity. Involved in positive regulation of transcription, DNA-templated and transcription by RNA polymerase II. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
HSD17B4 (HGNC:5213): (hydroxysteroid 17-beta dehydrogenase 4) The protein encoded by this gene is a bifunctional enzyme that is involved in the peroxisomal beta-oxidation pathway for fatty acids. It also acts as a catalyst for the formation of 3-ketoacyl-CoA intermediates from both straight-chain and 2-methyl-branched-chain fatty acids. Defects in this gene that affect the peroxisomal fatty acid beta-oxidation activity are a cause of D-bifunctional protein deficiency (DBPD). An apparent pseudogene of this gene is present on chromosome 8. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.
