The c.251C>T (p.T84M) alteration is located in exon 3 (coding exon 3) of the OBP2B gene. This alteration results from a C to T substitution at nucleotide position 251, causing the threonine (T) at amino acid position 84 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
