Genetic Variant FGF16:c.378+27_378+42delTTTTTTTTTTTTTTTT (chrX-77454272-GTTTTTTTTTTTTTTTT-G) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_003868.3(FGF16):c.378+27_378+42delTTTTTTTTTTTTTTTT variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000264 in 151,465 control chromosomes in the GnomAD database, with no homozygous occurrence. There are no hemizygote samples in GnomAD. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

FGF16 (HGNC:3672): (fibroblast growth factor 16) This gene encodes a member of a family of proteins that are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This gene is expressed in cardiac cells and is required for proper heart development. Mutation in this gene was also observed in individuals with metacarpal 4-5 fusion.
