The c.814A>T (p.T272S) alteration is located in exon 7 (coding exon 7) of the RBFA gene. This alteration results from a A to T substitution at nucleotide position 814, causing the threonine (T) at amino acid position 272 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
