Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2023The c.3283G>T (p.D1095Y) alteration is located in exon 22 (coding exon 21) of the PITPNM2 gene. This alteration results from a G to T substitution at nucleotide position 3283, causing the aspartic acid (D) at amino acid position 1095 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
