The c.710C>T (p.S237L) alteration is located in exon 4 (coding exon 4) of the MGARP gene. This alteration results from a C to T substitution at nucleotide position 710, causing the serine (S) at amino acid position 237 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
