The c.314T>G (p.L105R) alteration is located in exon 3 (coding exon 3) of the MS4A14 gene. This alteration results from a T to G substitution at nucleotide position 314, causing the leucine (L) at amino acid position 105 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
