Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.3844G>A (p.G1282S) alteration is located in exon 25 (coding exon 24) of the PITPNM2 gene. This alteration results from a G to A substitution at nucleotide position 3844, causing the glycine (G) at amino acid position 1282 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
