Genes affected

TLCD3B (HGNC:25295): (TLC domain containing 3B) This gene encodes a transmembrane protein, which may be a likely target of peroxisome proliferator-activated receptor gamma (PPAR-gamma). The product of the orthologous gene in mouse is related to obesity. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

C16orf92 (HGNC:26346): (chromosome 16 open reading frame 92) Predicted to be involved in fusion of sperm to egg plasma membrane involved in single fertilization. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.341C>T (p.A114V) alteration is located in exon 3 (coding exon 3) of the FAM57B gene. This alteration results from a C to T substitution at nucleotide position 341, causing the alanine (A) at amino acid position 114 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
