Variant summary

Our verdict is Benign. Variant got -14 ACMG points: 0P and 14B. BP4_Strong BP6_Moderate BS1 BS2

The ENST00000402432.4(FABP6):​c.62T>A​(p.Leu21His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00276 in 1,613,704 control chromosomes in the GnomAD database, including 112 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★). Synonymous variant affecting the same amino acid position (i.e. L21L) has been classified as Benign.

Genes affected

FABP6 (HGNC:3561): (fatty acid binding protein 6) This gene encodes the ileal fatty acid binding protein. Fatty acid binding proteins are a family of small, highly conserved, cytoplasmic proteins that bind long-chain fatty acids and other hydrophobic ligands. FABP6 and FABP1 (the liver fatty acid binding protein) are also able to bind bile acids. It is thought that FABPs roles include fatty acid uptake, transport, and metabolism. Transcript variants generated by alternate transcription promoters and/or alternate splicing have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0016603768).
• BP6: Variant 5-160229619-T-A is Benign according to our data. Variant chr5-160229619-T-A is described in ClinVar as [Benign]. Clinvar id is 768048.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.015 (2289/152142) while in subpopulation AFR AF= 0.0514 (2132/41494). AF 95% confidence interval is 0.0496. There are 63 homozygotes in gnomad4. There are 1080 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 63 AR gene
