The c.227C>T (p.S76L) alteration is located in exon 7 (coding exon 3) of the FAAP20 gene. This alteration results from a C to T substitution at nucleotide position 227, causing the serine (S) at amino acid position 76 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
