The c.1007C>T (p.T336M) alteration is located in exon 6 (coding exon 6) of the FAM131A gene. This alteration results from a C to T substitution at nucleotide position 1007, causing the threonine (T) at amino acid position 336 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
